Visual C# Express 2010 requested registry access is not allowed

Question

When I try to create a new project in VC# 2010, I get an error message that says " Requested registry access is not allowed". After searching through Google and MSDN, I found this link

http://www.texttoolkit.com/index.php?option=com_content&view=article&id=74:visual-studio-requested-registry-access-is-not-allowed&catid=35:technology&Itemid=55

explaining how to fix the problem. My issue is that I do not have the registry key described in this article. I am starting C# for a class in school, and I desperately need a working copy of the IDE. Any help is greatly appreciated. Thanks in advance.

Hi RB525,

Welcome to MSDN forums!

"explaining how to fix the problem. My issue is that I do not have the registry key described in this article"

-> In that Fix article, it's Visual Studio 2008 scenario, the corresponding registry key is HKEY_CLASSES_ROOT\VisualStudio.csproj.9.0.

http://www.texttoolkit.com/index.php?option=com_content&view=article&id=74:visual-studio-requested-registry-access-is-not-allowed&catid=35:technology&Itemid=55

However, you are using Visual Studio 2010 in your scenario, the corresponding registry key you find should be HKEY_CLASSES_ROOT\VisualStudio.csproj.10.0. Then please follow detailed fix steps inside to add user permission to the registry key.

 

After the fix, you should be able to create new C# project in Visual Studio 2010.

  

Best regards,

Martin Xie

Hi,

Using Sysinternal Process Monitor filtering on VBExpress.exe, VCExpress.exe and VCSExpress.exe (VB, C++, C#) and filtering for 'ACCESS DENIED'  changing the permissions on the following keys resolved this for me.

Give ownership to Administrators then everyone full contol on permissions.

For VS2010 C++ Express

HKCR\VCExpress.Launcher.vcproj.10.0

HKCR\VsWizard.VsWizardEngine.10.0\

HKCR\VsWizard.VsWizardEngine.10.0\CLSID

For VS2010 VB Express

HKCR\VBExpress.Launcher.vbproj.10.0

For VS2010 C#

HKCR\VCSExpress.Launcher.csproj.10.0

Hope this helps someone. At the very least you can download Sysinternals process monitor and resolve yourselves!

Yes Ray,

Great work, I too faced issue with Visual Web Dev 2010 and was not able to find any helpful, then tried *Express*!

It worked, but others shall try with *VWDExpress* to make sure they point only to required keys

 

Place below in a .cmd or .bat and run as Admin, And yes do get subinacl utility first.

<User_ID> =its ur user id

"C:\Program files\Windows Resource Kits\Tools\subinacl.exe" /keyreg HKEY_CLASSES_ROOT\*VWDExpress* /setowner=<UserID>

"C:\Program files\Windows Resource Kits\Tools\subinacl.exe" /keyreg HKEY_CLASSES_ROOT\*VWDExpress* /grant=<UserID>=F

 

Cheers from India

 

Answer 5

After a lot of trouble with this problem and having no success with any other solution I would like to explain a full-proof solution:

 

1.) Download Proccess Monitor

http://technet.microsoft.com/en-us/sysinternals/bb896645

2.) Open it and then try to create a Project in VS that generates the "Required Registry access is not allowed" message.

 

3.) Filter the messages where "Result" = "Access Denied"

 

4.) Find the one that is related to Visual Studio in my case : "HKCR\VCSExpress.Launcher.csproj.10.0"

 

5.) Navigate Regedit.exe to this Key and grant either permission to everyone or to your self.

 

I have seen this issue with various version of VS and this always allows me to to determine which Registry key is causing the problem.

This was driving me nuts - tried so many other fixes - none worked

THIS IS THE FIX!!

THANKS

Answer 7

I have installed Visual Studio 10.0 Professional today using a ‘normal’users account (suspect this might be the root of the issues)

Okay, this info is great – it allows me to see the fact that it is HKCR\VisualStudio.Launcher.vbproj.10.0 is one of the MANY Visual Studio files which is causing problems with Access denied.

I am now trying to edit the registry keys associated with Visual Studio, however:

When I attempt to edit the permissions within regedit, I am presented with:

VisualStudio.Launcher.vbproj.10.0 cannot be opened. An error is preventing this key from being opened. Details:
Accessis Denied. It confounds me that as Administrator, I cannot grant permissions to (one of the ) registry keys that is causing the issue.

I am inclined to do a full uninstall then reinstall as Administrator to see if it addresses the problem......
