The error is not Visual Studio installation but a Windows 7/Server 2008 change in security as the administrator account does not automatically run with elevated priviledges. The installer for the project needs to be changed but it is a small change. I have
submitted this as an issue and how to change it.
The workaround for installing on Windows 7/Server 2008 is to
1. Write cmd in the search box under the Start button
2. Rightclick on the cmd in the list and choose Run as Administrator
3. Log in as admin or press ok elevated security
4. Install from the prompt. This way you install from the Admin account with elevated priviledges
