qmake problem after reinstallation

[xtlc]

I reinstalled QT 5.2 and now I cant really get it back up and running.

I first downloaded the MSVC12 version, didnt work, so I tried again with the online installer. I always get the message: ":-1: error: Qt Creator needs a compiler set up to build. Configure a compiler in the kit options.". When I go to options -> build & run -> kits I see:

I want to use the MSVC2012 amd64 or 32 version, like I did before. But how do I get them working? I always end up seeing: "No compiler can produce code for this Qt version ...". What did I do wrong?
