Windows 7 x64, cant use SDK Browser

Hi

I try to start cuda programming. Im clompltetly new in cuda. I was programmin C and C++ and other stuff since years, and now, for university, i should learn cuda.

But the problems start before programming ;-)

I cant open the “GPU Computing SDK Browser”. Windows 7 just says the program has stoped working.

So i tried to reinstall the program, but this doesnt work, because he wanted first to reinstall the old program. And this doesnt work, because i have no rigths of some files. I run the uninstall as admin too, but same error.

So how can i uninstall this program?

cu, Dieter
