Ok, thanks to superman and sorren for your quick answers. I had already tried them but I finally figured out my problem
Anyway, the problem above resulted from another problem I had.
I had to download SDK 7.1 and then i had to change the platform toolset (configuration properties -> general -> platform toolset) to windows 7.1SDK. Make sure to also have the correct library folder linked in additional library directories (linker -> general).
When you've downloaded windows SDK7.1, do the following:
windows start menu -> microsoft windows SDK7.1 -> visual studios registration -> window SDK version ->7.1 or 7.1A
