C# – 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:

  1. Running Visual Studio as Administrator
  2. Running aspnet_regiis.exe -ga MyUserName
  3. 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?

Best Solution

On Windows 8 Pro:


On Windows 7 and 8.1 and 10


(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.
