There can be so many answers to that question, it's impossible to answer. You'll have to give more information.

Ok. I try to explane. with my english))

I wrote a program (cleint-server) on XP with MSVS2005. So, it's working on XP-machines. When I trying to run client on Vista - Vista closing application. I tryed to debug using MessageBox. Boxes appeares in defferent places. but in one function alwayse with one of param equals 1. I can post a code - but my question in another. Why the same code is working on XP, but not working on Vista? Is this project properties, or API - finctions not working on Vista?

Does a Debug built version also crash?

Have you installed your dev tools on Vista and tried to reproduce the crash?

If those don't work, keep the PDBs from your build and generate a crashdump on Vista, then load it up in Visual Studio. At the very least, you'll get a stack trace. A full dump will also give you symbol values.
