Windows 8.1 fresh install of iTunes 11.1.3: Error 7 (Windows error 193)

Question

Hi.
I have installed Windows 8.1 yesterday. I downloaded and installed iTunes64 11.1.3, but when I try to start it I get this:
iTunes
iTunes was not installed correctly.  Please reinstall iTunes.
Error 7 (Windows error 193)
OK  
I browsed several sites describing similar problems. But uninstalling/reinstalling every related to Apple (even with Revo Uninstaller) did not help. Dot-Net Framework is build in in Windows 8, so http://support.apple.com/kb/ts3074 does not help.
Any ideas?
Cheers, Tobias
