Read Excel File from Both x86 and x64 - c#

My local PC is installed with Windows7 64bit and Microsoft Excel 2010
But most of my clients' PC are XP Professional Service Pack 3 and Excel 2003
I got this connection string for import data of Excel file
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\MyExcel.xls;Extended Properties="Excel 8.0;HDR=Yes;IMEX=1";
But this throws an error saying that
The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.
I want my application can read Excel file on both, x86 and x64, architectures.
How can i handle this programmatically without installing extra Excel driver on PC?
I'm thinking to use different connection strings for importing Excel files based on CPU archtiecture.
Is there any better idea?

Make sure you have installed the Jet driver that supports both x86 and x64 on your development system.
Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine

This is because of a mismatch between compilation configuration in Visual Studio and the ACE version installed on the system. (Ref: How to read or write excel file using ACE OLEDB data provider?.)
You can resolve it by making sure that both are same. Compile your app using the x64 bits if 64-bit ACE is installed or use 32-bit ACE.

do i need to install ACE driver on the production environment?

So I'm getting this error that ACE OleDb is not registered on my local machine. As far as I'm aware, it is an installable driver. Do i need to install this on my target machine assuming it doesn't have it? BTW it's an Excel import.

Windows Server 08 Standalone exe Microsoft.Jet.OLEDB.4.0 error

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

Microsoft.jet.oledb.4.0 error on windows 7

I have folllowing things on my PC
Windows 7 (64bit OS)
Microsoft Office 2003
Microsoft Visual c# Express 2008
I have two projects on this system. In one project MS Access is connecting though Microsoft.Jet.OLEDB.4.0 provider, but in second project it gives error, says "Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine."
I need some help...
Thanks in Advance..
You have to compile your C# application to x86. "Any CPU" or "x64" is not an option since the Jet Ole DB driver/provider is not available for 64-bit systems, only for 32-bit.

Alternative to Microsoft.Jet.OLEDB.4.0 for 64 bit access on MDB File

I have like many others the problem that I can't access Microsoft Access (MDB Files) from my 64 bit machine using Microsoft.Jet.OLEDB.4.0.
I know that there's no 64bit version of it, and that I need to compile it against x86.
So my question is:
Do you know any other .NET Providers for Microsoft Access that supports 64bit access?
To get 64 bit Microsoft Access drivers download the Microsoft Access Database Engine 2010 Redistributable. You cannot install that with a 32 bit version of Microsoft Office installed.
The ODBC connection string with that driver is "Driver={{Microsoft Access Driver (*.mdb, *.accdb)}};Dbq=%FILE_NAME%;Uid=Admin;Pwd=;". The OleDb connection string for that driver is "Provider=Microsoft Office 12.0 Access Database Engine OLE DB Provider;Data Source=%FILE_NAME%;User Id=admin;Password=;.
For Windows server 2003, there is the MSDASQL that offer an OLEDB provider for ODBC, which can connect to Access. It is available in 64bits.

Have you ever had this error?

microsoft visual studio opens my table using dataset designer
but i cannot open my table using the same connectionstring.
my database is DBase IV.
and this is the connectionstring
Driver={Microsoft dBASE Driver
(*.dbf)};collatingsequence=ASCII;dbq=d:\Data\88;deleted=0;driverid=277;fil=dBase
IV;maxbuffersize=2048;maxscanrows=8;pagetimeout=600;safetransactions=0;statistics=0;threads=3;uid=admin;usercommitsync=Yes
it is made by visual studio itself.
and this is my code
DataSet1TableAdapters.AN10TableAdapter _AN10TableAdapter = new DataSet1TableAdapters.AN10TableAdapter();
_AN10TableAdapter.Fill(D_Data.AN10);
and this is the error
ERROR [IM002] [Microsoft][ODBC Driver
Manager] Data source name not found
and no default driver specified
this real joke is killing me.
platform:vista x64
language:c#.net
.netframework vesion:3.5
worked on it:10 days
I guess the issue is the 64-bitness of your machine. The driver is an unmanaged component and you probably have a single version of it (32-bit or 64-bit) installed on your machine. Since you cannot load 32-bit unmanaged components in a 64 bit process (and vice versa), it'll not work. Switch the target CPU setting of your project to x64 and x86 to force the assembly to run with the appropriate bitness and retry. It's likely to solve your problem.
Do you have the dBase data sources installed?
Control Panel -> Administrative Tools -> Data Sources (ODBC)
System DSN tab
(My OS is Windows XP but that's the idea.)
