Unable to run C++ on windows

Hi Guys,
I’m using C++ and recently I’ve been unable to run it on my windows 7.
It starts up then this message pops up:
Error:
Microsoft Visual C++ Runtime Library
Runtime Error!
Program: C:Program FilesATI MultimediamainATIDtct.EXE
This application has requested the Runtime to terminate it in an unusual way. Please contact the application’s support team for more information.
I recently upgraded from XPSP.
Could that be the problem?
Thanks.
