I'm trying to get data from an Excel file on a button click event. My connection string is:
string connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\source\\SiteCore65\\Individual-Data.xls;Extended Properties=Excel 8.0;";
When I click on the button, I got the following error:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.
I have no clue how to fix this. My operating system is Windows 7.
Well, you need to install it. You're looking for:
The 2007 Office System Driver: Data Connectivity Components.
A 64-bit version of the 'Microsoft Access Database Engine 2010 Redistributable' that will allow you to use the 'Microsoft.ACE.OLEDB.12.0' provider is available here:
http://www.microsoft.com/en-us/download/details.aspx?id=13255
If you use the download from the accepted answer, you will need to build for x86, as pointed out by #backtestbroker.com.
depending on the app(32/64bit) using the connection you could just install
Access 2007 engines (only 32bit)
Access 2010 (32&64bit)
Access 2013 full runtime (32&64bit ! >200mb)
Access 2016 runtime
Access 2019 runtime
Summary:
all offices from 2007-2016 contain the provider "Microsoft.ACE.Oledb.12.0"
depending on your application architecture choose the appropriate runtime engine (32/64)6
check your providers with the powershell-command from both 32 and 64bit shell:
(New-Object system.data.oledb.oledbenumerator).GetElements() | select SOURCES_NAME, SOURCES_DESCRIPTION
and you will see which provider your system can use
the long story:
the strings can be found with http://live.sysinternals.com/strings.exe
eg. on a 64bit System with 32bit drivers installed
strings.exe -u -n 10 "c:\Program Files (x86)\Common Files\microsoft shared\OFFICE12\MSO.DLL" | findstr "ACE.O"
strings.exe -u -n 10 "c:\Program Files (x86)\Common Files\microsoft shared\OFFICE14\MSO.DLL" | findstr "ACE.O"
strings.exe -u -n 10 "c:\Program Files (x86)\Common Files\microsoft shared\OFFICE15\MSO.DLL" | findstr "ACE.O"
even in the upcoming office 2016
c:\Program Files\Microsoft Office\root\VFS\ProgramFilesCommonX64\Microsoft Shared\OFFICE16\MSO.DLL
c:\Program Files\Microsoft Office\root\VFS\ProgramFilesCommonX86\Microsoft Shared\OFFICE16\MSO.DLL
you will find the strings
Microsoft.ACE.OLEDB
Microsoft.ACE.Oledb.12.0
the Office 2013 comes also with csi.dll
c:\Program Files (x86)\Common Files\microsoft shared\OFFICE15\Csi.dll
c:\Program Files\Common Files\Microsoft Shared\OFFICE15\Csi.dll
which contains the "Microsoft.ACE.OLEDB.15.0"
and Office 2016
c:\Program Files\Microsoft Office\root\VFS\ProgramFilesCommonX64\Microsoft Shared\OFFICE16\Csi.dll
c:\Program Files\Microsoft Office\root\VFS\ProgramFilesCommonX86\Microsoft Shared\OFFICE16\Csi.dll
which has the "Microsoft.ACE.OLEDB.16.0" version
The first thing you need to check is your build configuration of your application.
If you have built your project under x86 platform, then in order to
resolve you issue you should install the following packages on your
machine:
In order to use the 'Microsoft.ACE.OLEDB.12.0' provider you must
install the Microsoft Access Database Engine 2010 Redistributable
first, this installation is available at:
http://www.microsoft.com/download/en/details.aspx?id=13255 .
After the installation has complete, try running you application, if this
solves the issue great, if not, continue to step 2.
This next step is an unexplained workaround, which works for Office
2010, even though it is the Data Connectivity Components of Office 2007. I am not quite sure why this works, but it does and this has been proven to work in almost all cases. You need to install the 2007 Office System Driver: Data Connectivity Components, this installation is available at:
http://www.microsoft.com/download/en/confirmation.aspx?id=23734 .
After this installation is complete, try running your application, this should resolve the issue.
If you are trying to run an application built under x64 or AnyCPU
platform, I would recommend first validating that it runs as expected
under the x86 platform. In the event that it does not run under that
x86 platform, perform the steps in the first part and validate that
it runs as expected.
I did read that the MS Access drivers including the OLEDB Database
driver works only under the x86 platform and is incompatible under
the x64 or AnyCPU platform. But this appears to be untrue. I
validated my application was running when building x86, then I
installed the Access Database Engine using the passive flag.
First download the file locally You can download the installation
here: http://www.microsoft.com/en-us/download/details.aspx?id=13255
Installing using the command prompt with the '/passive' flag. In
the command prompt run the following command:
'AccessDatabaseEngine_x64.exe /passive'
After these 2 steps I managed to run my application after building in
x64 or AnyCPU build configuration. This appeared to solve my issue.
Note: The order of the steps seems to make a difference, so please follow accordingly.
I got this error/exception in Visual Studio 2010 when I changed my build in the Configuration Manager dialog box from "x86" to "Any CPU". This OLEDB database driver I understand only works in x86 and is not 64bit compatible. Changing the build configuration back to x86 solved the problem for me.
I installed the MS drivers and it still didn't work for me. Then I found this blog post that solved the issue. Read it there, else use these two images (linked from that post) as the TLDR sumamary:
Although many answers have been given, the problem I encountered was not yet mentioned.
My Scenario: 64-Bit Application, Win10-64, Office 2007 32-Bit installed.
Installation of the 32-Bit Installer AccessDatabaseEngine.exe as downloaded from MS
reports success, but is NOT installed, as verified with the Powershell
Script of one of the postings above here.
Installation of the 64-Bit installer AccessDatabaseEngine_X64.exe reported a shocking error message:
The very simple solution has been found here on an Autodesk site.
Just add the parameter /passive to the commandline string, like this:
AccessDatabaseEngine_X64.exe /passive
Installation successful, the OleDb driver worked.
The Excel files I am processing with OleDb are of xlsx type, produced with EPPlus 4.5 and modified with Excel 2007.
For all those still affected by this.
I've been getting the error...
OLEDB error "The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine."
...as described by the OP, Shailesh Sahu.
I have 64bit Windows 7.
My problem is within PowerShell scripts, but is using a connection string, similar to the OP's post, so hopefully my findings can be applied to C#, PowerShell and any other language relying on the "Microsoft.ACE.OLEDB" driver.
I followed instructions on this MS forum thread: http://goo.gl/h73RmI
I first tried installing the 64bit version, then installing the 32bit version of the AccessDatabaseEngine.exe from this page
http://www.microsoft.com/en-us/download/details.aspx?id=13255
But still no joy.
I then ran the code below in PowerShell (from SQL Panda's site http://goo.gl/A3Hu96)
(New-Object system.data.oledb.oledbenumerator).GetElements() | select SOURCES_NAME, SOURCES_DESCRIPTION
...which gave me this result (I've removed other data sources for brevity)...
SOURCES_NAME SOURCES_DESCRIPTION
------------ -------------------
Microsoft.ACE.OLEDB.15.0 Microsoft Office 15.0 Access Database Engine OLE DB Provider
As you can see, I have Microsoft.ACE.OLEDB.15.0 (fifteen) not Microsoft.ACE.OLEDB.12.0 (twelve)
So, I amended my connection string to 15 and it worked.
So, a quick PowerShell snippet to demonstrate how to soft-code the version...
$AceVersion = ((New-Object System.Data.OleDb.OleDbEnumerator).GetElements() | Where-Object { $_.SOURCES_NAME -like "Microsoft.ACE.OLEDB*" } | Sort-Object SOURCES_NAME -Descending | Select-Object -First 1 SOURCES_NAME).SOURCES_NAME
$connString = "Provider=$AceVersion;Data Source=`"$filepath`";Extended Properties=`"Excel 12.0 Xml;HDR=NO`";"
amended to pick the latest ACE version, if more than one
Hopefully, anyone finding this can now check to see what OLEDB version is installed and use the appropriate version number.
If you're using 64-bit but still having problem even after installing AccessDatabaseEngine, see this post, it solved the problem for me.
i.e. You need to install this AccessDatabaseEngine
You need to change the Solution Platform from "Any CPU" to "x86" or "x64" based on the bitness of office installation.
The steps are given below:
Right click on the Solution File in Solution Explorer:
Click on the Configuration Manager.
Click on the Active Platform Drop down, if x86 is already there then select that, else click on New.
Select x86 or x64 from the new platform dropdown:
Compile and run your application.
do this 2 steps:
in this menu: project -> yourproject properties... -> Build : uncheck "prefer 32-Bit"
in connectionString : write cuotes before and after Extended properties, like this: Extended Properties='Excel 12.0 Xml;HDR=YES'
var fileName = string.Format("{0}", openFileDialog1.FileName);
var connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0}; Extended Properties='Excel 12.0 Xml;HDR=YES'", fileName);
var adapter = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", connectionString);
var ds = new DataSet();
adapter.Fill(ds, TableNmae);
DataTable data = ds.Tables[TableNmae];
dg1.DataSource = data;
I was able to fix this by following the steps in this article: http://www.mikesdotnetting.com/article/280/solved-the-microsoft-ace-oledb-12-0-provider-is-not-registered-on-the-local-machine
The key point for me was this:
When debugging with IIS,
by default, Visual Studio uses the 32-bit version. You can change this
from within Visual Studio by going to Tools » Options » Projects And
Solutions » Web Projects » General, and choosing
"Use the 64 bit version of IIS Express for websites and projects"
After checking that option, then setting the platform target of my project back to "Any CPU" (i had set it to x86 somewhere in the troubleshooting process), i was able to overcome the error.
If you are debugging a web project, just make sure IIS Express is running either in 32 or 64 bits depending on your project settings.
Goto
Tools > Options > Projects and Solutions > Web Projects
and from there check (or uncheck) the 'Use 64 bit version of IIS Express...'
If the installed "AccessDatabaseEngine" still does not help, below is solution:
You need to change the Active Solution Platform from "Any CPU" to "x86".
OLEDB Provider is Not Registered on the Local Machine
From CodeProject.com
First verify which version of microsoft.ace.oledb.12.0 is installed in your system.
Check in below path C:\Program Files\Common Files\Microsoft Shared\OFFICE14\ACEOLEDB.DLL --64 bit is installed
Check in below path C:\Program Files (x86)\Common Files\Microsoft Shared\OFFICE14\ACEOLEDB.DLL --x86 bit is installed
If (x86) is installed then using configuration manager change solution platform to x86, for x64 change to x64.
If not available then install using below link
https://www.microsoft.com/en-us/download/details.aspx?id=23734
A 64-bit version of the 'Microsoft Access Database Engine 2010 Redistributable' that will allow you to use the 'Microsoft.ACE.OLEDB.12.0' provider is available here:
http://www.microsoft.com/en-us/download/details.aspx?id=13255
If using VS 2012 or later, make sure that "Prefer 32-bit" checkbox is unchecked in the project's Properties => Build => General configuration
syp_dino,
The solution for me as you suggested for the "Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine" error is to change the Active Solution Platform from "Any CPU" to "x86".
When I performed those steps, rebuilt the solution, grabbed the EXE and placed in on the network, everything worked smoothly on the Windows 7 64 bit machine.
I faced this same problem. Go to the Solution Properties and change Any CPU to x86, I think it will do the job.
These configurations worked in January of 2020 on my new machine build:
(1 - x64 only) Windows 10 x64, Office 365 x64, AccessDatabaseEngine_x64 2016 installed with /passive argument, VStudio build settings set to x64 explicitly, with the following connection string: Provider= Microsoft.ACE.OLEDB.16.0; Data Source=D:...\MyDatabase.accdb
(2 - x64 or x32) Windows 10 x64, Office 365 x64, AccessDatabaseEngine_x64 2016 installed with /passive argument, PLUS AccessDatabaseEngine 2010 (32bit) installed with /passive argument, VStudio build settings set to AnyCPU, with the following connection string: Provider= Microsoft.ACE.OLEDB.16.0; Data Source=D:...\MyDatabase.accdb
(3 - x32 only) Windows 10 x64, Office 365 x32, AccessDatabaseEngine 2010 (32bit) installed with /passive argument, VStudio build settings set to x86, with the following connection string: Provider= Microsoft.ACE.OLEDB.12.0; Data Source=D:...\MyDatabase.accdb
FAILURE NOTES
Using the ACE.OLEDB.12.0 x64 provider in the connection string failed with only the AccessDatabaseEngine_x64 2016 installed as above in (1).
Using AnyCPU in the visual studio build settings failed in (1). Setting x64 is required. Maybe this is because AnyCPU means that Vstudio must see an x32 ACE.OLEDB.nn.0 provider at compile time.
The ACE.OLEDB.12.0 2016 x32 /passive engine would NOT install when it saw x64 applications around. (The ACE.OLEDB.12.0 2010 x32 /passive installer worked.)
CONCLUSIONS
To use x64 build settings, you need to have the 2016 x64 database engine AND the ACE.OLEDB.16.0 connection-string provider AND explicit x64 build settings to work with Office 365 in January of 2020. Using the /passive option makes installations easy. Credit to whoever posted that tip!
To use AnyCPU, I needed to have both the ACE.OLEDB.12.0 2010 x32 engine and the ACE.OLEDB.16.0 x64 engines installed. That way Vstudio could see both x32 and x64 engines at "AnyCPU" compile time. I could change the provider connection string to ACE.OLEDB.12.0 for x32 operation or to ACE.OLEDB.16.0 for x64 operation. Both worked fine.
To use x86 build settings, you need to have the 2010 x32 database engine AND the ACE.OLEDB.12.0 connection-string provider AND explicit x86 build settings to work with Office 365 x32 in January of 2020.
I have similar issue when we are reading Excel file.
History of the problem:
We recently migrated our application from 32-bit to 64-bit because of the memory requirement. For that we migrated our windows 7 from 32-bit to 64-bit. But still we installed 32-bit office on our machines.
because, of this we had this issue while importing Excel data into application.
Solution,
I downloaded 64-bit version of the http://www.microsoft.com/en-us/download/details.aspx?id=13255 and installed with argument as,
AccessDatabaseEngine_x64.exe /passive
Without any code change my issue get resolved.
Note:
On 64-bit OS and 64-bit office, my functionality was working fine without this fix. This fix is only required while our application is 64-bit running on 64-bit OS which is having 32-bit office installed on it.
I had this issue when attempting to import data from an excel file (xlsx) into a SQL Server DB using SSMS 2014.
The 2007 Office System Driver: Data Connectivity Components install did the trick for me.
I received this error when importing data from an Excel file into MS-SQL.
The provider was already installed (64-bit) and this surprised me why it didn't work.
So all I did was locate the Import/Export application used here i.e. the .EXE.
And I found it at
C:\Program Files\Microsoft SQL Server\130\DTS\Binn\DTSWizard.exe
I then ran the .exe directly to perform the data import. And it worked!
I followed the instructions set out by others; installing this patch, installing that patch as well as the Microsoft Access Database Engine 2010.
My issue was that I'm using the same library (linq2sql) in 2 sites on my machine; 1 works and 1 doesn't.
Eventually I found that I had to "enable 32 bit applications" in the advanced settings of the apppool for my non-working site.
Everything works fine now.
Just download & install the following Access DB engine (X86 or X64: as per your machine configuration) and see the magic :)
https://www.microsoft.com/en-us/download/confirmation.aspx?id=13255
If you get this error when trying to use ACE from an ASP.NET application, the most likely cause is that you have installed either one of the 32-bit versions. By default, IIS on a 64-bit operating system will run applications in a 64-bit worker process. 64-bit processes cannot load 32-bit DLLs. When a call is made to the ACE provider, the 64 bit process will attempt to locate a 64-bit DLL. If it doesn't exist, you get the error message that brought you here.
In this case you have two options. First, you can install the 2010 64-bit version. If you have the 2007 32-bit version installed, you can simply install the 2010 64-bit version alongside it. If you have the 32-bit version of 2010 installed, you need to uninstall it and download and install the 64-bit 2010 version instead. You cannot have both the 32- and 64-bit versions of the 2010 provider installed at the same time. If you are performing the installation on your development machine, you may also be constrained by the bit-ness of any existing Office installations.
The second option is to change the application pool in IIS to enable 32-bit applications. If you are using the full version of IIS, you can use the management tool to do this (Control Panel » Administrative Tools » Internet Information Services (IIS) Manager).
For more understanding please refer below link
for Visual Studio 2022 (and newer)
I had this error every time and it didn't help anything. VS2019 was the solution.
https://learn.microsoft.com/en-us/visualstudio/data-tools/accessing-data-in-visual-studio?view=vs-2022#data-providers
If you're using Visual Studio 2022 to connect to databases, you will
need to be aware that Visual Studio 2022 is a 64-bit process. This
means some of the data tools in Visual Studio will not be able to
connect to OLEDB or ODBC databases using 32-bit data providers.
If you need to maintain 32-bit applications that connect to OLEDB or
ODBC databases, you will still be able to build and run the
application with Visual Studio 2022. However, if you need to use any
of the Visual Studio Data Tools such as Server Explorer, Data Source
Wizard, or the DataSet Designer, you will need to use an earlier
version of Visual Studio that is still a 32-bit process. The last
version of Visual Studio that was a 32-bit process was Visual Studio
2019.
also can try these steps
In the SQL Server,
1.Open one data base
2.Clic in the option 'Server Obtect'
3.Clic in 'Linked Servers'
4.Clic in 'Providers'
5.Clic Rigth in 'Microsoft.ACE.OLEDB.12.0'
6.Uncheck all the options and close
I had the same issue but in this case microsoft-ace-oledb-12-0-provider was already installed on my machine and working fine for other application developed.
The difference between those application and the one with I had the problem was the Old Applications were running on "Local IIS" whereas the one with error was on "IIS Express(running from Visual Studio").
So what I did was-
Right Click on Project Name.
Go to Properties
Go to Web Tab on the right.
Under Servers select Local IIS and click on Create Virtual Directory button.
Run the application again and it worked.
I had Microsoft Access Database Engine 2010 Redistributable already installed on my machine but was still receiving the Microsoft ACE OLEDB Provider error.
Then I recalled that I had upgraded to Office 2016 recently, so, may be I should try reinstalling Microsoft Access Database Engine 2010 Redistributable. And that fixed the problem on my machine.
So, if you have upgraded to different version of MS Office or even repaired/reinstalled your MS Office then try reinstalling Microsoft Access Database Engine 2010 Redistributable before wasting time with finding other fixes. Good luck!
1.) Verify your connection string with ConnectionStrings.com.
2.) Make sure you have the correct database engine installed. These were the two database engines that helped me.
Microsoft Access Database Engine 2010 Redistributable
2007 Office System Driver: Data Connectivity Components
3.) There could be an issue with your build target platform being "Any CPU", it may need to be "X86" (Properties, Build, Platform Target).
I created a windows application developed in .NET 3.5 in a 32 bit Windows 2008 server. When deployed the application in a 64 bit server it shows the error "Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine ".
So as a solution to this issue, i have changed the build property of the project to X86, so that it will build in 32 bit mode, and rebuild the project in the 32bit machine. But, the same project uses other DB drivers (DB2, SQL etc.) to connect to other databases. So when i deployed my app again in the 64 bit OS, it throws the exception " Attempted to load a 64-bit assembly on a 32-bit platform. "
I am using the Microsoft.Jet.OLEDB.4.0 driver to read and write to the Excel (.xls)
I found a solution for this problem. The issue I described in my question occured basically due to the incompatibility of the Microsoft.Jet.OLEDB.4.0 driver in 64 bit OS.
So if we are using Microsoft.Jet.OLEDB.4.0 driver in a 64 bit server, we have to force our application to build in in 32 bit mode (This is the answer I found when I did an extensive search for this known issue) and that causes other part of my code to break.
Fortunately, now Microsoft has released a 64 bit compatible 2010 Office System Driver which can be used as replacement for the traditional Microsoft.Jet.OLEDB.4.0 driver. It works both in 32 bit as well as 64 bit servers. I have used it for Excel file manipulation and it worked fine for me in both the environments. But this driver is in BETA.
You can download this driver from Microsoft Access Database Engine 2010 Redistributable
If the issue persist in ASP.NET,All I had to do was change the "Enable 32-bit Applications" setting to True, in the Advanced Settings for the Application Pool.
I have the same problem
Microsoft.Jet.OLEDB.4.0' provider is not registered on the local
machine
I applied the answer by neo but it did not work until I change the provider to “Provider=Microsoft.ACE.OLEDB.12.0;” in connection string.
Hope this will help if some one face the same issue.
I know it's quite old questions and many persons has answered. but I am summarizing the things for understanding:
If the file extension is xls and OS is 32 bit then only you can use "Microsoft.Jet.OLEDB.4.0". Microsoft has not released 64 bit version of this driver.
If file extension is xlsx or OS is 64 bit then you must have to use "Microsoft.ACE.OLEDB.12.0". The application compiled in 32/64 bit mode does not impact the selection of driver.
Always install the 64 bit driver of Microsoft.ACE.OLEDB.12.0 on OS 64 bit. If you have already installed Office 32 bit then you need to run driver from cmd with /passive argument. This hack works till Office 2013 only, Microsoft stopped this workaround from Office 2016 for Microsoft.ACE.OLEDB.16.0 drivers.
AccessDatabaseEngine_x64.exe /passive
Download drivers Microsoft.ACE.OLEDB.12.0
private void ProcessFile(string path)
{
string connString = string.Empty;
if (Path.GetExtension(path).ToLower().Trim() == ".xls" && Environment.Is64BitOperatingSystem == false)
connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"";
else
connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\"";
}
If Application is compiled with AnyCPU flag, it will look for 64 bit Access drivers on 64 bit OS and 32 bit access drivers on 32 bit OS.
If your application runs on localIIS, You can solve this problem by enabling 32-bit applications in AppPool's Advanced Settings
I've the same message, I have a webpage with do on visual studio 2010, I read a file.xls on that page,in my project visual has not any problem, when I put it on my IIS local throw me a 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine'
,I fixed that problem next following this steps,
1.-Open IIS
2.-Change the appPool on Advanced Settings
3.-true to enable to 32-bit application.
and that's all
ps.I changed Configuration Manager to X86 on Active Solution Platform
I had the same issue. I changed the application configuration to x86, then it worked!
I just Changed my Property of project into x64 format
Project---> Properties--->Build--->Target Framework---> X64
We have come across this issue in desktop app.
Dev Environment:
Windows 7 Ultimate - 64 bit
.Net Framework 4.5
Provider=Microsoft.Jet.OLEDB.4.0
It has been resolved by changing Platform target to X86 from Any CPU.
Project Properties >> Build >> Platform Target.
I ran into this issue with my desktop application ('Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine). I did not have the option to build as a 32 bit app. Hoping this would help others in the same situation.
I did the following and the issue went away:
Installed the 64 bit version of Microsoft Access Database Engine
2010 Redistributable, as suggested by neo
Changed my provider to Microsoft.ACE.OLEDB.12.0
Although a more optimal solution is to simply recompile as suggested above, that requires access to the source code. In my case, I only had the finished .exe and had to use this solution. It uses CorFlags.exe from the .Net SDK to change the loading characteristics of the application.
Download the .Net Framework SDK (I personally used 3.5, but the version used should be at or above the required .Net for your application.
When installing, all you need is CorLibs.exe, so just check Windows Development Tools.
After installation, find your CorFlags.exe. For my install of the .Net Framework 3.5 SDK, it was at C:\Program Files\Microsoft SDKs\Windows\v7.0\Bin.
Open a command prompt and type path/to/CorFlags.exe path/to/your/exeFile.exe /32Bit+.
You're done! This sets the starting flags for your program so that it starts in 32 bit WOW64 mode, and can therefore access microsoft.jet.oledb.4.0.
Change in IIS Settings application pool advanced settings.Enable 32 bit application
Just Change the property based on your machine and all have done :-)
Project---> Properties--->Build--->Target Framework---> X64
or
Project---> Properties--->Build--->Target Framework---> X86
I have changed my connection string from
var myConnectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Persist Security Info=True;Jet OLEDB:Database Password=;",gisdbPath);
to this:
var myConnectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Mode=Share Deny None;Data Source={0};user id=Admin;password=;", gisdbPath);
It works fro me never asked for Microsoft.Jet.OLEDB.4.0'registered.
There is indeed no 64 bit version of Jet - and no plans (apparently) to produce one.
You might be able to use the ACE 64 bit driver:
http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=23734
but I have no idea how that would work if you need to go back to Jet for your 32 bit apps.
However, you may be able to switch the project to 32bit in the Express version (I haven't tried and don't have 2008 installed in any flavour anymore)
there is a thread here that talks about it:
http://xboxforums.create.msdn.com/forums/t/4377.aspx#22601
Maybe it's time to scrap Access databases altogether, bite the bullet and go for SQL server instead?
I'm using VS2013 for Winforms, the below solution worked for me.
Download : http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=23734
Then Set VS Target Platform to x86.
In older versions of IIS, you will not find Advance Settings so to enable Enable 32-bit Applications you have to execute the following commands:
cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
and
%SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i

started SQL Server 2014 Import and Export Data (32-bit) instead of 64-bit and it is working for me. I haven't changed any IIS setting and not installed any extra software.
I know that I have this problem over and over when I deploy my application on a new server because I'm using this driver to connect to a Excel file. So here it is what I'm doing lately.
There's a Windows Server 2008 R2, I install the Access drivers for a x64 bit machine and I get rid of this message, which makes me very happy just to bump into another.
This one here below works splendidly on my dev machine but on server gives me an error even after installing the latest ODBC drivers, which I think this is the problem, but this is how I solved it.
private const string OledbProviderString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\\OlsonWindows.xls;Extended Properties=\"Excel 8.0;HDR=YES\"";
I replace with the new provider like this below:
private const string OledbProviderString = #"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\OlsonWindows.xlsx;Extended Properties='Excel 12.0;HDR=YES;';";
But as I do this, there's one thing you should notice. Using the .xlsx file extension and Excel version is 12.0.
After I get into this error message Error: "Could Not Find Installable ISAM", I decide to change the things a little bit like below:
private const string OledbProviderString = #"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\OlsonWindows.xls;Extended Properties='Excel 8.0;HDR=YES;';";
and yes, I'm done with that nasty thing, but here I got another message The Microsoft Access database engine cannot open or write to the file 'time_zone'. It is already opened exclusively by another user, or you need permission to view and write its data. which tells me I'm not far away from solving it.
Maybe there's another process that opened the file meanwhile and all that I have to do is a restart and all will take start smoothly running as expected.
go to Start->Run and type cmd
this starts the Command Prompt
(also available from Start->Programs->Accessories->Command Prompt)
type cd .. and press return
type cd .. and press return again (keep doing this until the prompt shows :> )
now you need to go to a special folder which might be c:\windows\system32 or it might be c:\winnt\system32 or it might be c:\windows\sysWOW64
try typing each of these eg
cd c:\windows\sysWOW64
(if it says The system cannot find the path specified, try the next one)
cd c:\windows\system32
cd c:\winnt\system32
when one of those doesn't cause an error, stop, you've found the correct folder.
now you need to register the OLE DB 4.0 DLLs by typing these commands and pressing return after each
regsvr32 Msjetoledb40.dll
regsvr32 Msjet40.dll
regsvr32 Mswstr10.dll
regsvr32 Msjter40.dll
regsvr32 Msjint40.dll
There isn't a 64 bit provider for Jet. If you want to support multiple DB sources including Jet to Excel you will need at least that part of your application to run in a 32 bit process.
The error you are getting when you compile for x86 is a bit strange. I can't see how you would end up referencing 64 bit assemblies in this case.
I have a standalone application used for CRON that I deployed to a Windows Server 2008 machine that keeps giving me the error below.
System.InvalidOperationException: The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.
I did some research on the subject and it seems a 64 bit application does not work with the MSJet dll for 64bit. So the solution was to recompile the application and have it targeted for a 32bit machine, however I cannot do that in my project. I looked the in the C:\Windows\SysWOW64 folder and found both the msjet40.dll and msjetoledb40.dll files. Is there any other way I can run this application as is or maybe in a compatibility setting since I cant target it to 32 bit when I build it.
You cannot use msjet40.dll or msjetoledb40.dll if your application is a 64-bit process. You will have to use the ACE OLEDB 12.0 which is the only real alternative that supports 64-bit process. Your only other option is to compile the application as a 32-bit process.
You can download this driver from: Microsoft Access Database Engine 2010 Redistributable and if you are looking for additional information you can find it here
I was trying to built a asp.net web app with the connection string defined in the webconfig file. When I try to debug I am getting the following exception:
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
The connection string looks like this:
connectionString="Driver={MySQL ODBC 5.1 Driver};server=XX.XX.XX.XX;port=3306;database=db_name;user=username;pwd=pass;option=3;" providerName="System.Data.Odbc"/>
The driver is installed and I can see it listed in the 'ODBC Data Source Administrator'.
I tried changing the build configuration to 'Any CPU', still it failed.
Can somebody help me out to figure whats going on here??
Thanks,
Uday
If you have installed the x64 version of the ODBC driver you can use it compiling the executable as default (both CPU) otherwise you have to compile the executable as x86 only and use the x86-32 driver.
Keep in mind that by default on x64 os an application compiled as both CPU (x64 and x86) will use the 64bit version of the driver, this means that if you install the 32bit version of the ODBC driver and compile the executable as Both CPU or x64 you will get the error, so you have to compile the application only x86.
You could configure VS to use IIS instead of the internal one, plus you would get more experience configuring IIS correctly for your web app (i.e. Windows Server 2k8 R2 has pretty drastic configuration/security differences than previous versions). If you configure your AppPool to run under 64 bit then your code should also run in 64 bit mode.
I created a windows application developed in .NET 3.5 in a 32 bit Windows 2008 server. When deployed the application in a 64 bit server it shows the error "Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine ".
So as a solution to this issue, i have changed the build property of the project to X86, so that it will build in 32 bit mode, and rebuild the project in the 32bit machine. But, the same project uses other DB drivers (DB2, SQL etc.) to connect to other databases. So when i deployed my app again in the 64 bit OS, it throws the exception " Attempted to load a 64-bit assembly on a 32-bit platform. "
I am using the Microsoft.Jet.OLEDB.4.0 driver to read and write to the Excel (.xls)
I found a solution for this problem. The issue I described in my question occured basically due to the incompatibility of the Microsoft.Jet.OLEDB.4.0 driver in 64 bit OS.
So if we are using Microsoft.Jet.OLEDB.4.0 driver in a 64 bit server, we have to force our application to build in in 32 bit mode (This is the answer I found when I did an extensive search for this known issue) and that causes other part of my code to break.
Fortunately, now Microsoft has released a 64 bit compatible 2010 Office System Driver which can be used as replacement for the traditional Microsoft.Jet.OLEDB.4.0 driver. It works both in 32 bit as well as 64 bit servers. I have used it for Excel file manipulation and it worked fine for me in both the environments. But this driver is in BETA.
You can download this driver from Microsoft Access Database Engine 2010 Redistributable
If the issue persist in ASP.NET,All I had to do was change the "Enable 32-bit Applications" setting to True, in the Advanced Settings for the Application Pool.
I have the same problem
Microsoft.Jet.OLEDB.4.0' provider is not registered on the local
machine
I applied the answer by neo but it did not work until I change the provider to “Provider=Microsoft.ACE.OLEDB.12.0;” in connection string.
Hope this will help if some one face the same issue.
I know it's quite old questions and many persons has answered. but I am summarizing the things for understanding:
If the file extension is xls and OS is 32 bit then only you can use "Microsoft.Jet.OLEDB.4.0". Microsoft has not released 64 bit version of this driver.
If file extension is xlsx or OS is 64 bit then you must have to use "Microsoft.ACE.OLEDB.12.0". The application compiled in 32/64 bit mode does not impact the selection of driver.
Always install the 64 bit driver of Microsoft.ACE.OLEDB.12.0 on OS 64 bit. If you have already installed Office 32 bit then you need to run driver from cmd with /passive argument. This hack works till Office 2013 only, Microsoft stopped this workaround from Office 2016 for Microsoft.ACE.OLEDB.16.0 drivers.
AccessDatabaseEngine_x64.exe /passive
Download drivers Microsoft.ACE.OLEDB.12.0
private void ProcessFile(string path)
{
string connString = string.Empty;
if (Path.GetExtension(path).ToLower().Trim() == ".xls" && Environment.Is64BitOperatingSystem == false)
connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + path + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"";
else
connString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + path + ";Extended Properties=\"Excel 12.0;HDR=Yes;IMEX=2\"";
}
If Application is compiled with AnyCPU flag, it will look for 64 bit Access drivers on 64 bit OS and 32 bit access drivers on 32 bit OS.
If your application runs on localIIS, You can solve this problem by enabling 32-bit applications in AppPool's Advanced Settings
I've the same message, I have a webpage with do on visual studio 2010, I read a file.xls on that page,in my project visual has not any problem, when I put it on my IIS local throw me a 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine'
,I fixed that problem next following this steps,
1.-Open IIS
2.-Change the appPool on Advanced Settings
3.-true to enable to 32-bit application.
and that's all
ps.I changed Configuration Manager to X86 on Active Solution Platform
I had the same issue. I changed the application configuration to x86, then it worked!
I just Changed my Property of project into x64 format
Project---> Properties--->Build--->Target Framework---> X64
We have come across this issue in desktop app.
Dev Environment:
Windows 7 Ultimate - 64 bit
.Net Framework 4.5
Provider=Microsoft.Jet.OLEDB.4.0
It has been resolved by changing Platform target to X86 from Any CPU.
Project Properties >> Build >> Platform Target.
I ran into this issue with my desktop application ('Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine). I did not have the option to build as a 32 bit app. Hoping this would help others in the same situation.
I did the following and the issue went away:
Installed the 64 bit version of Microsoft Access Database Engine
2010 Redistributable, as suggested by neo
Changed my provider to Microsoft.ACE.OLEDB.12.0
Although a more optimal solution is to simply recompile as suggested above, that requires access to the source code. In my case, I only had the finished .exe and had to use this solution. It uses CorFlags.exe from the .Net SDK to change the loading characteristics of the application.
Download the .Net Framework SDK (I personally used 3.5, but the version used should be at or above the required .Net for your application.
When installing, all you need is CorLibs.exe, so just check Windows Development Tools.
After installation, find your CorFlags.exe. For my install of the .Net Framework 3.5 SDK, it was at C:\Program Files\Microsoft SDKs\Windows\v7.0\Bin.
Open a command prompt and type path/to/CorFlags.exe path/to/your/exeFile.exe /32Bit+.
You're done! This sets the starting flags for your program so that it starts in 32 bit WOW64 mode, and can therefore access microsoft.jet.oledb.4.0.
Change in IIS Settings application pool advanced settings.Enable 32 bit application
Just Change the property based on your machine and all have done :-)
Project---> Properties--->Build--->Target Framework---> X64
or
Project---> Properties--->Build--->Target Framework---> X86
I have changed my connection string from
var myConnectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};Persist Security Info=True;Jet OLEDB:Database Password=;",gisdbPath);
to this:
var myConnectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0;Mode=Share Deny None;Data Source={0};user id=Admin;password=;", gisdbPath);
It works fro me never asked for Microsoft.Jet.OLEDB.4.0'registered.
There is indeed no 64 bit version of Jet - and no plans (apparently) to produce one.
You might be able to use the ACE 64 bit driver:
http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=23734
but I have no idea how that would work if you need to go back to Jet for your 32 bit apps.
However, you may be able to switch the project to 32bit in the Express version (I haven't tried and don't have 2008 installed in any flavour anymore)
there is a thread here that talks about it:
http://xboxforums.create.msdn.com/forums/t/4377.aspx#22601
Maybe it's time to scrap Access databases altogether, bite the bullet and go for SQL server instead?
I'm using VS2013 for Winforms, the below solution worked for me.
Download : http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=23734
Then Set VS Target Platform to x86.
In older versions of IIS, you will not find Advance Settings so to enable Enable 32-bit Applications you have to execute the following commands:
cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 1
and
%SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i
