Access to the registry key is denied (ABCPdf) - c#

I am trying out ABCPdf 8.1 and when using the AddImageUrl(...) method I get the following error:
Access to the registry key 'HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl' is denied.
I have looked in the registry and main\featurecontrol does not exist for CURRENT_USER so I cannot change permissions on it.
Has anyone experienced this before, or know of any solutions I could try?
Thanks in advance

Who is the CURRENT_USER? Assuming it's an ASP.NET application identity, have you tried loading its user profile?
Open up IIS Manager and navigate to the application pool for your site. In the Advanced Settings dialog, set Load User Profile to True.

Perhaps it's a problem between IE9 and ABCPDF.If this error comes by using AddHtml() or AddImageHtml() , I suggest you to change the Rendering Engine from MSHtml to Gecko.
theDoc.HtmlOptions.Engine = EngineType.Gecko;

In my case, this solution solved my error.

If you know the specific key that ABCPDF is trying to add, and you don't want to change the app pool settings, you can set the appropriate key in HKEY_LOCAL_MACHINE. We had exactly that situation and knew that ABCPDF wanted to add the FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI key. So we added the entries below to the registry. Note that the second key is specifically for 32-bit applications running on 64-bit Windows.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI]
"w3wp.exe"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_IVIEWOBJECTDRAW_DMLT9_WITH_GDI]
"w3wp.exe"=dword:00000001

I'm not sure if this is the answer but if you are trying to access this programaticaly your executable should run as administrator while accessing it. If you are in debug mode run visual studio as administrator (right click and select "Run as administrator"

IIS Web API cannot be accessed [duplicate]

I want to upload my own asp.net website on IIS with IIS Manager. But when I do this, I get the following error
HTTP Error 500.19 - Internal Server Error The requested page cannot be
accessed because the related configuration data for the page is
invalid
Module IIS Web Core
Notification Unknown
Handler Not yet determined
Error Code 0x80070005
Config Error Cannot read configuration file due to insufficient permissions
Config File \\?\C:\Users\Yasso\Documents\Visual Studio 2008\WebSites\WebSite5\web.config
I searched many times for a solution for this error, but none of the solutions solved the error.
I have a problem with my IUSR account. I can't see this account in the "group or user names" in the properties of the web.config.
What is the problem?
This can also happen if the site is configured to use the IIS URL Rewrite module but it is not installed.
Finally, I got the solution for my problem. The ASP.net account did not appear in the IIS manager, because I didn’t check its checkbox in IIS. To do this in Windows 7 follow the steps:
Open control panel
Click on “program” link (not uninstall programs)
Click “turn windows features on/off” link
Locate “Internet Information services IIS” in the pop up window and expand its node
Expand the “World Wide Web Service” node
Expand “Application Development Features” node
Check the check box of “ASP.NET”
Then click ok button
Now, you will see the ASP.net account on the IIS manager and by default you will see the IIS account. Now, you should move your ASP.net website from “my document” to another place where the IIS have permission to access it (i.e. to another partition on your computer). Now, browse your website from the IIS manager and it should work.
Thanks a lot for Jeff Turner for the solution.
The message is saying that your configuration file is corrupt in some way. However it also says that it can't actually access the config file. So I'd ignore the original message about corruption/lack of validity as this is most likely just the effect of not being able to read the file due to a lack of authorization.
The reason it cannot read the config file is because the process running your web app does not have permission to access the file/directory. So you need to give the process running your web app those permissions.
The access rights should be fairly straightforward, i.e. at least Read, and, depending on your app, maybe Write.
Above, you mention IUSR etc. not being in the properties for web.config. If by that you mean that IUSR is not listed in the security tab of the file then it's a good thing. One doesn't want to give IUSR any kind of permission to web.config. The role IUSR is an anonymous internet user.
The file web.config should only be accessible through your application.
The problem is you haven't said which OS and IIS version you are using so it's difficult to advise which steps to take.
I.e. in IIS 7.5, the error message you're quoting is likely to occur due to your ApplicationPoolIdentity not being assigned the permissions. Your web application belongs to an application pool and so you need to give the permissions to the OS account that your web application's application pool runs under. Often this is something like NetworkService but you may have customized it to run under a purpose made account. Without more info it's difficult to help you.
I was having the same problem, here is the solution that worked for me.
IIS Manager
Right clicked on that Website
Edit Permissions
Added user 'IIS_IUSRS' from Security tab
Gave full permissions to User 'IIS_IUSRS'
Set the Application Pool's Identity to 'ApplicationPoolIdentity'
For Visual Studio (VS) developers:
As hinted at by Harvey Darvey, Savage, and Snives, your Application Host Configuration may be pointing to the wrong application physical path. Search for virtualDirectory within /.vs/config/applicationhost.config to change the physicalPath if it is incorrect.
Make sure the physicalPath is correct:
Just to chip in, I received the same kind of error and my problem was quite simple: I was missing the .NET Core Hosting Bundle. Once I installed the tool and restarted the server, it was fine.
You can find the manual to host asp.net core on windows here: https://learn.microsoft.com/en-us/aspnet/core/host-and-deploy/iis/?view=aspnetcore-2.2
To resolve this, make sure you installed the hosting bundle.
https://dotnet.microsoft.com/download/dotnet-core/3.1
Facepalm alert:
You will also get this error if the path to the config file is wrong. Double-check it to make sure the physical path is entered correctly in IIS.
You need to assign permissions for IIS_IUSRS on the local machine (but you don't have to assign for IUSR, in fact it will work even if you explicitly deny permissions).
To assign permissions, just right click on the folder and on the security tab make sure to grant the correct permissions, and if the user is not listed then click "ADD", and enter IIS_IUSRS (and make sure that under "domain" the local computer is selected, or enter in the name field YourLocalComputerName\IIS_IUSRS), and then you are good to go.
If you want you can instead of assigning permissions to the IIS_IUSRS group, you can instead assign to the app pool which should in general be "IIS APPPOOL\ app pool name".
The same thing happened with me , Try checking this by double clicking on the Connection strings on the right pane of IIS 7 when you select a website.
It will give you an error (that there is some problem with web config file), because you have used URL rewrite rules and the respective component is not installed.
Install “Microsoft URL Rewrite Module 2.0 for IIS 7” and this should fix your problem
Install ASP.NET Core module
Download the installer using the following link:
https://www.microsoft.com/net/permalink/dotnetcore-current-windows-runtime-bundle-installer
Nothing here worked for me, I found this command in another SO answer though and it solved my problem. Just start command prompt as an administrator and run this command:
run->cmd
run "c:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i"
Credit: User Vicxx
Ehm. I had moved my site/files to a different folder. Without changing the path in the IIS website.
You may all laugh now.
I do these steps to solve this problem in
Windows Server 2012, IIS 8.5. Should work for other versions too.
Go to server manager, click add roles and features
In the roles section choose: Web Server
Under Security sub-section choose everything (I excluded digest, IP restrictions and URL authorization as we don't use them)
Under Application Development choose .NET Extensibility 4.5, ASP.NET 4.5 and both ISAPI entries
In the features section choose: NET 3.5, .NET 4.5, ASP.NET 4.5
In the web server section choose: Web Server (all), Management Tools (IIS Management Console and Management Service), Windows
Make sure you have the application pool set to the correct version of the framework. You'll also need to make sure your aspnet, IIS_IUSRS, or IUSR users have read access to the application's directory.
Try installing the 'Application Development' sub component of IIS as mentioned in this SO
Click "Start button" in the search box, enter "Turn windows features
on or off"
in the features window, Click: "Internet Information
Services"
Click: "World Wide Web Services"
Click: "Application
Development Features"
Check (enable) the features. I checked all but
CGI.
One other possibility that fixed this problem for me:
IIS -> Edit Permissions -> Security Tab -> Give "Users" appropriate permissions (or IIS_IUSRS, depending on your setup)
This also happened to me when I had a default document of the same name (like index.aspx) specified in both my web.config file AND my IIS website. I ended up removing the entry from the IIS website and kept the web.config entry like below:
<system.webServer>
<defaultDocument>
<files>
<add value="index.aspx" />
</files>
</defaultDocument>...
Sometimes this message has can be missing components in your IIS environment e.g. a particular framework, or an IIS feature like dynamic compression, rather than permissions to web.config.
If this is the case, a solution can be to install and use the Microsoft Platform Installer and install those missing components - you might have to take a stab at what exactly is missing because the error log and message don't tell you.
Actually, any missing module can lead to this problem. In my case, it was CORS Module. So read the web.config and seek for any addon module that you specified in it and check that it is installed, or install it otherwise. Unfortunately, the error message does not help finding the problem at all.
Pretty straight forward, IIS doesn't have access to your web.config. I'd start by taking the site out of your documents folder. Verify it has r/w permissions then as well.
You need to set permission for your Website folder or copy they to wwwroot folder :)
- If set permission, have 2 way:
+ Right click to Your Website folder
+ Or right click to Your Website in IIS
=> select Edit permission and Add a permission (IUSR - default iis user)
Good luck ;-)
You can get this error if you have a synax error or issue in your web.config file.
For me, it was a stray ampersand in a URL that I was using in the AppSettings.
In my case, it caused by application physical path point to a non-existent folder in IIS.
got this problem with mapped drives, IIS doesn't work with mapped drives. Just use the unmapped drive.
I had the issue as I copied my web.config file down from prod, changed everything not prod related except the Rewrite rules which were rewriting to httpS.
Removed those rules and ran fine.
I too had the similar issue and i fixed it by commenting some sections in web.config file.
The project was earlier built and deployed in .Net 2.0. After migrating to .Net 3.5, it started throwing the exception.
Resolutions:
If your configuration file contains "<sectionGroup name="system.web.extensions>", comment it and run as this section is already available under Machine.config.
On the IIS 7.5 error page you get click on 'View more Information' at the bottom of the page and in this case it will take you to the following Microsoft link:
http://support.microsoft.com/kb/942055
The 0x80070005 Error Code seems to be permissions related and following the steps in Resolution 2, Method 2 assigning the correct accounts with permissions on relevant folders should fix it - I spent 3 days looking for a solution until I came across it, worked straight after.
Explore the folder where your website is store and see you will get one extra folder "aspnet_client" delete that folder and it will work for you.
I tried this my problem is solved.
If it works for you please make it as answer so that some body else will also get solution.
None of this worked for me, but I finally have a solution which worked for me:
remove this line in web.config:
<compilation debug="true" targetFramework="4.5"/>
don't remove this line
<compilation debug="true"/>

BarTender Error: Retrieving the COM class factory for component with CLSID in Asp.Net

I selected the BarTender from Com tab on preferences screen and add BarTender into my project.
when I execute the project with Ctrl+F5 on my local computer I can print the barcode smoothly.
But when I publish my project under wwwroot I get an error as follows,
Also I set the project platform “ x86 – x64 Any Cpu” but nothing was changed.
PS: I am giving the screenshots as links because of I have not enough points. Sorry for this
It's an EXE server, so it looks like you need to give Local Launch and Local Activation permissions to the COM Class for the identity that your web site is running under. You can do this with DCOMCnfg.exe. Have a look at the Application Pool identity and make sure it has the appropriate rights. A good way to test the problem is to set it to "EVERYONE". If that works then it's definately your problem, but DO NOT leave it set to "EVERYONE". Once you've proven this is the issue, you'll need to set the activation, launch and probably access permissions correctly.
This is due to the security settings on the library itself. I had the same issues with Excel & Illustrator COM's.
Even though this is Excel, this site will guide you through setting the security and permissions.
UPDATE:
If you can't find the library then it may be a 32 bit one; these don't always show up in 64 bit console (assuming you're running 64 bit..) - if so, you need to launch the 32 bit DCOMCONFIG. See bottom of the page here on how to launch 32 bit version.

Error - Unable to access the IIS metabase

After installing Visual Studio 2012 and opening my solution I get a series of errors in this form:
The Web Application Project Foo is configured to use IIS.
Unable to access the IIS Metabase. You do not have sufficient privilege to access IIS web sites on your machine.
I get this for each of our web applications.
Things I have tried:
Running Visual Studio as Administrator
Running aspnet_regiis.exe -ga MyUserName
Running aspnet_regiis.exe -i
These seem to be common solutions for this problem but I have not had any success with them.
Is there anything else I can try to do?
On Windows 8 Pro:
%systemroot%\inetsrv\config
On Windows 7 and 8.1 and 10
%systemroot%\System32\inetsrv\config
(Where %systemroot% is usually C:\Windows)
Navigate to the appropriate location above in Windows Explorer. You will be blocked access with a popup which says:
"You don't have access to this folder - Click continue to permanently get access to this folder"
Click 'continue' for this folder, and with the Export folder underneath. I changed the shortcut back to "Run as me" (a member of the domain and local administrators ) and was able to open and deploy the solution.
I think you are not running visual studio with administrator permissions. Look that:
http://bloggingabout.net/blogs/rick/archive/2012/10/04/unable-to-access-the-iis-metabase.aspx
To quote
The solution to this is simple: start your Visual Studio with "Run as
Administrator". You can do this by right clicking the shortcut and
selecting "Run as Administrator".
I think we encountered a similar problem at work. For us, the solution was to go into Control Panel -> Programs and Features -> Turn Windows Features on or off... inside that, we had to select Internet Information Services -> Web Management Tools -> IIS 6 Management Compatibility -> IIS Metabase and IIS 6 configuration compatibility.
Give that a try and let me know if it helps!
Note: We're running IIS 7.5 on Windows 7 using both Visual Studio 2005 and 2010 and doing stuff with super-old-school WebServices (.asmx)...
I resolved this issue by granting IIS AppPool identity permissions to the %systemroot%\inetsrv\config
If you are working on a project which does not require the use of IIS, then a workaround to open the project with this error is to simply right click on the unloaded project and click edit, search for:
<ProjectExtensions>
<VisualStudio>
<FlavorProperties GUID="">
<WebProjectProperties>
<UseIIS>True</UseIIS>
</WebProjectProperties>
</FlavorProperties>
</VisualStudio>
</ProjectExtensions>
</Project>
and set USEIIS to false
<UseIIS>False</UseIIS>
reload the project by right clicking on it after saving changes.
I have had two seperate types of problem lead to this error, and thought I'd share...
1. The directory was on an network share and due to UAC restrictions, was
unable to be accessed -- even when running as an admin.
2. The directory was on a drive that didn't exist...
Both of these stem from an unfortunate (imo) choice by MS to put things in the Documents or My Document directory, combinee with really lousy error messages. In both of the above cases the fundamental problem was that the IISExpress Config file goes in My Documents, and it either didn't exist or couldn't be accessed.
Thank you to everyone that answered. Since this was closed for a long time I couldn't provide much feedback, but I did eventually fix my problem. I tried many of these other solutions and they didn't fix my issue, but I'm sure they help when the root cause is different.
My Solution
I solved this problem by turning off the IIS and .Net Framework features within Windows 7 and then turning them back on. It seems like this re-installation is what fixed my issue. I still don't know what caused the problem, but at least one other developer on my team had the same issue.
Navigating to folder: %systemroot%\System32\inetsrv\config presents a security dialog. Click continue and this may resolve the issue. This has worked on two separate Win 10/VS 2017/IIS machines.
On a windows 81, from an admin command prompt, use:
icacls "C:\Windows\System32\inetsrv\config" /t /grant "IIS AppPool\DefaultAppPool":(R)
Then go back in VS, right click on the failed project, choose Reload.

I had this problem - the symptoms were the same, but the issue I had was that I had set the "My Documents" folder to be on a network share, and the share was not accessible.
The root problem was that the IIS config files located at %USERPROFILE%\Documents are not accessible. Once I changed the "My Documents" folder location (I modified the reg value), it started working again.
I know that this may not be a common scenario that you might run into, but I've posted it here because it gives the same symptoms.
I came across this today and fixed the problem by removing the IISUrl from the Project file:
Right click project
Click Edit
Delete the following line:
<IISUrl>http://localhost:xxxxx </IISUrl>
Reload project
Now add a new IIS virtual directory by right clicking Project > Properties > Web and selecting Use Local IIS Web Server (Uncheck Use IIS Express) and clicking the Create Virtual Directory button.
You might run across this problem and have same problem as me. I "solved" it before and then power outage and computer crashed, not sure why a registry setting reverted but it is the SOURCE of my problem.
I tried all the running as adminstrator
All the IIS / IIS express re-installs.
Various "hacks"
Came down to having to fix the registry again.
Could not as administrator even open regedit (Need to access registry since problem is not with gpedit.msc admin template )
UnHookExec.inf on desktop
Just save UnHookExec.inf and install it by right clicking and selecting install. Installing the file will not show any popup or notice box.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Personal pointing to non-existant fileshare. Changing that to local path solved this problem for me. – Pasi Savolainen Jul 14 '14 at 8:41
(changed from \\cs2data\home\stickelt\my documents to c:\dev )
Now ALL is good and Visual Studio opened solution with 15 projects and connects to IIS and does not complain about not being able to access iis metadata
I had never ran into this before, as nobody at current job had this problem ( many have been here a long time, some got clones of other machines that "worked" and many are on another domain etc.. )
I just had this issue today and I found that I didn't open VS as 'Run as Administrator'.
After doing this, I was able to publish the Service.
If you have administrator permissions, Right Click to Visual Studio icon > properties and then advanced, "Run as administrator" check.
You can run visaul studio as administrator directly anymore.
This way, formal and so basic.
In addition to the answer by #nologo, I also had to use IIS. So I changed the
<UseIIS>True</UseIIS>
to 'False' first.
Opened the solution and ensured that the project could be loaded.
Close solution and that instance of Visual Studio
Change the value to 'True' again
Open the solution.
This time, I didn't get any error/warning. I could also run with Ctrl+F5 or F5 without any problem while my project was mapped to an IIS website.
Changing this key worked for me:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Personal
The location didn't exist.
Go to the root directory of your project and find the following file:
YourProjectName.csproj.user - inside it, make sure UseIISExpress is set to false:
<UseIISExpress>false</UseIISExpress>
If that alone doesn't work try the following as well and try again:
YourProjectName.csproj - inside the main project file, make sure both UseIIS and UseIISExpress are set to false:
<UseIIS>True</UseIIS>
<UseIISExpress>false</UseIISExpress>
After changing these I was able to load the project again.
Note: Make sure you run your VS as an Administrator, as mentioned in the other answers.
I also had a similar problem. My solution is an extension to the answer "Run as admin" which I hope someone might find useful.
I was running VS2012 and almost every time I had to do the Right Click, Run As Administrator. I got tired of this so instead I went into its properties on the shortcut, clicked advanced, and then clicked the "Run as Administrator" option. Now VS2012 always runs as administrator whenever I open it from that shortcut.
The from that shortcut bit is important. I proceeded to branch my project, and download the branch to a new local folder. Then, when I opened it from the shortcut I had no problem. But if I went directly into the folder, and ran the project locally without the shortcut, it did not run as administrator and I got this error.
Once I opened VS2012 as usual first, then using File/Open/Project It worked again no problem. (because I was running as admin). But I wasn't running as admin when I opened the solution using windows file manager.
The other suggestions seem somewhat extreme, but this is pretty simple so I would tend to give this a try first.
Hope this was helpful.
This seems like one of those "All errors lead to this message" type of bugs.
Mine was that the App Pool was just turned off. I turned it back on, and everything worked fine.
One more thing you could try:
Check if you have pending Windows updates.
If you do, please reboot before trying anything else.
I tend to never shut down my machine, so I had plenty of them waiting for a reboot. And that fixed it.
I tried everything above. The credit goes to all of the responses above. Having tried all of the suggestions on their own, I just assembled this combination of suggestions in an order that made sense to me. Note my Documents folder is on a shared drive. The subst/IISExpress stuff is not applicable unless you're in the same boat.
Configure VS to run as admin
Uninstall IIS via Add/Remove Programs, Windows Features
Reboot
Run WinRAR or something similar as admin and archive C:\windows\system32\inetsrv\
Run cmd as admin and rmdir /s c:\windows\system32\inetsrv\ to completely remove all traces of the last install. Leave elevated cmd prompt open for later.
Reinstall IIS with IIS 6 Metabase compatibility (doubt this was necessary)
Leave Default AppPool and Default Website as-is (I had previously deleted both)
Ran C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ga MYDOMAIN\scottt732
Ran C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
Also, because my Documents folder is on a share drive, I was having IIS Express issues. I don't use/like IIS Express, but Visual Studio complained about it.
From elevated cmd prompt, ran subst U: c:\Temp. Created C:\Temp\Documents\ and copied the IISExpress folder from my U drive.
Created CustomUserHome key in HKCU\Software\Microsoft\IISExpress with C:\Temp\Documents\IISExpress
This allowed me to get Visual Studio to open my web projects and edit the properties. I tweaked the projects to store web server settings in a user file and adjusted it to use a Custom URL (not sure if this was necessary)
I may/may not have to run the subst command each time I restart. Don't care.
And after throwing in the towel 3 times and spending roughly ~6 hours I can open web projects in Visual Studio (2015 Update 2).
I just had the same issue with me today. And I found it annoying. Though I have other two websites already under development from the same IIS but still was not able to create new site. Strange, but I did this.
Delete the site from IIS
Create new site, give it a name "new_site"
Select Application Pool other than the site name itself. So it wont be messing up with default settings.
Keep IP "unassigned" if you are running it from same machine
give it some unused port
Run Visual Studio as "Run as Administrator" by right-clicking on VS executable shortcut.
You are done!
You do not need to turn off/re-install anything other than what I have stated since it works.
Let me know if anybody had the same issue just like me and solved the same way. I think it was not the issue but a wrong way of creating website on localhost which Visual Studio rejects to open.
I hope this will help newbies.
Create a shortcut to the "devenv.exe"
select the "Run as administrator" option for the shortcut
doble click on the short cut and reopen your project
I had the same problem after Adding feature from this link afterward I followed this article the issue was gone.
I did a repair of Visual Studio 2015 to solve this.
The repair took a long time, but it solved the issue while doing much of the above did not. I am running Win 7 enterprise.
Open visual studio command prompt and type below command and run
aspnet_regiis -ga machinename\ASPNET
After running the above command Reset the IIS and test the application that resolve your issue.
If above command doesn’t resolve your problem then try to run below command in visual studio command prompt:-
aspnet_regiis -i
Alternatively we can run above command from our windows command prompt also
Go to the Start menu and open Run and enter and click OK
%windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe –I
After that Reset the IIS and test the application that resolves your issue
In Visual Studio 2015:
I changed UseIIS in .csproj file to false and it worked for me.
<UseIIS>False</UseIIS>
In my message, beside complaining about "Unable to access the IIS metabase", it also mentions can't access "<IISUrl>http://localhost:6416/</IISUrl>". Right click on the unload project, click Edit, find the line "<IISUrl>http://localhost:6416/</IISUrl>", comment it out. Reload and it should work. This has to do with administrator doesn't have permission to access that address.
I had a similar problem. Visual Studio would not load any web projects and showed the error: creation of virtual directory <myproj:myport> failed. Unable to access the IIS metabase.
In my case it was actually IISExpress that was at the root of the problem. Right clicking on IIS Express in Programs and Features in the control panel and choosing repair fixed the issue in less than two minutes.
I'm using Win 8 Pro and VS 2013.
After trying everything in this page... I simply reinstalled IIS Express 8 and everything works fine now (even without running as an admin).
My conclusion is that this is a rather generic error and there are multiple root causes.

Access error in Windows 7

I am working on a windows appliciation in which i create a folder at runtime and save some xml files in the folder....
Every thing works fine in Windows XP but when i run this in Widows 7 / Vista i get the error saying Access to the path is denied..
i am creating the folder in C:\Programfiles\MyApplication\
Please help me in resolving this
Windows 7 (and Vista) set access permissions on the Program Files directories and will not allow a normal user to write to those directories.
Either your program has to be run by an administrator, or you can change the permissions on your app's Program Files entry, or save the data somewhere else.
It might be an idea to use the special folders .NET provides for this type of data. This should work:
Directory.CreateDirectory(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + #"\AppName\test folder");
Then write your data to this folder.
Is your application running in the context of administrator?
Is visual studio running as administrator?
To do this right click VS and select run as administrator, to do it permanently, right click, propertys and select the run as admin check box.
When your debugging your app through VS, it will need the permissions, else the application its self will.
Its probably just a permissions based thing...
You can enable XP mode for an executable.

Long time Windows XP developers should consider reading UAC,
http://en.wikipedia.org/wiki/User_Account_Control
It was first added in Windows Vista, and now becomes a central part of Windows family.
You SHOULDN'T write to Program Files. It's a bad habit and only installers should write there. What you "want" is bad for the whole ecosystem and just plain wrong. Don't do it.

Create Registry Value In Local Machine Using C#

I'm trying to save an install path to the registry so my windows service will know where my other application was installed.
I'm using visual studio's deployment to create a registry value in HKEY_CURRENT_USER, but my windows service which runs under LocalMachine doesn't have access to that. I then made the installer create a registry value in HKEY_LOCAL_MACHINE, but when I view the registry after the install it appears it never made the value. Any ideas?
Turns out that it was written to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ instead of HKEY_LOCAL_MACHINE\SOFTWARE\ because I'm running 64 bit windows.
You dont need to make one of your own. The msi will actually set one for you, it can be found in
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{ProductGUID}\InstallLocation
EDIT
I have just had a look and it appears that it doesn't get set every time...
It's possible that you don't have the installer set to ask for privilege elevation, and that it's installing it in the per-user virtualized registry.
Check HKEY_CLASSES_ROOT\VirtualStore\Machine. If your key is there, you need to set your installer to ask for elevation.
