I didn't post the exact error, because I thought it was due to the test version. I'll give it another try tomorrow then.
Edit:
Now I installed the Windows SDK, but it still won't work. Unfortunately I installed the Visual Studio in german and the only language options are "german" and "as in Windows" which amounts to the same thing, unless I swtich the OS language....
I opened up the file "projects\MSVC_2011\FreeSpace2.sln" and tried to rightclick-> compile "FreeSpace.ccp", I tried "Erstellen" which translates to "create" on both the Bold "FreeSpace2" and the Projectmap itself and lastly I tried "create batch" on the project map (where I selected the three release inferno builds). Everytime I get the same error message between 1 and 19 times.

In case it helps, I'll try to translate as best I can:

This particular error message is the last of 19 similar messages (differing only in the first line) when I used "create batch".
