I do Vista. And this has also its peculiarities.
I think the standard trick is to reinstall the non working program.
Then reinstall the OS.
This is actions that doesn't need any special skills. If this doesn't work either, then you have to call support for the software in question and see what they will say about the problem. If they has a fix for the problem, they send it to you. But often enough they cannot help you. Then you are on your own. If the software is important enough perhaps you would buy another computer and pray that the software works on that one.
