The first thing you need to do is look at where it is failing and try to understand why. This may be a change in the operating system from XP, but it may also be a bug in your code that has only just come to light. Without seeing the failing code it is impossible to guess.

Most of the reasons an application that runs fine on XP but will fail on Vista/Windows 7 has to do with new tighter security requirements for the newere OSs. Some things that you could do regarding file placement, rgeistry access, and other things are simply not allowed on the newer OSs. In the end tough, it's difficult to tell exactly why an app is broken on Win7. Your only hope is to have the source code so you can debug it. If you don't, you're essentially screwed, or at the very least, pressed up against the willingness of the manufacturer to update a piece of software that's at least a decade old.

You can also try to run the application in compatibility mode to see if it fix the problem.
