I ran into the same problem when converting to TFS 2010 2 nights ago. Adding C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE to the Path environment variable on the build servers worked; however; that was not the only error I received. I was also
receiving the following error when running
Exit Code 100. Nothing Succeeded: Team Foundation Server [tfsservername] does not exist or is not accessible at this time.
Technical information (for administrator):
The request failed with HTTP status 403: Forbidden.
The reason was that it was executing tf.exe undo using the VS2008 tools path
Executing c:\Program Files\Microsoft Visual Studio 9.0\Common7\Tools\..\IDE\tf.exe undo
Without knowing that TFS 2010 was not yet supported, I looked at the documentation and found the Version parameter. I passed
without changing anything else, it fixed the problem and started using the VS2010 tools path.
I’m using version 4.0 of the Build Extension Pack.
