Designer.exe does not start

Hello!
I want to try Qt with VS 2010. Thus I downloaded the sources and compiled them (on a VS x64 command prompt with configure -platform win32-msvc2010 -no-qt3support & nmake). It seems like it worked (got no errors and a lot libs and dlls where created)

My problem: When I go into the qt bin folder and try to start Designer.exe the program instantly crashes (with the typical "you want to send a report to microsoft? window).
I can start qtdemo.exe, and most of the demos start. But many of them crash too when I click on certain contrails. For example I can launch Layouts->Dynamic Layouts application, but when I click on the orientation combobox the program crashes.
Do I have to do another step after configure & nmake to use Qt?

Oh, another thing: In the Qt lib folder are all the import libs .lib and .dll files. Don't I have to copy all the DLLs into a Win32 system folder to make them accessible for all apps?
Thanks

No, never copy the DLLs in the Win32 system folder. You'll just end up with DLL hell, and much more trouble than your getting now.

Windows 7 (and possibly Vista) will not even allow you to modify a directory such as that one. Its reserved for the OS, let the OS manage it.
