"The selected file is not a valid solution file" error when trying to open source safe database

I recently re-built my development machine which now uses windows 7. On this new machine, VS 2010 can no longer open sln files directly from SS 2005. These are valid 2010 solutions (orginally created witih VS 2010) that worked fine until I re-built my machine. My co-workers have the same setup and do not have this problem.

The message I get is "The selected file is not a valid solution file".

I've re-built many times and used many installs of VS and never had a problem opening sln's from SS using VS 05, 08 or 10. I've just never seen this before. My co-workers have not had this problem either

I have re-installed SS 2005 as well as the latest SS update but nothing works.

VS 2010 can open solutions from the file system just fine, so it must be a SS thing.

Any ideas?

I've had a similar error message after installing Windows 7. Turns out that some features of Visual Studio were not yet installed. It might have been a service pack or EF4. Once that was installed, I was able to open the solution file. Then, I was also getting "The project type is not supported by this installation" until I installed some other updates, like for MVC3.

I presume that the solution file had information that the un-patched Visual Studio did not recognize.
