Question : Need Help Debugging an AppCrash

Need Help in tracking down an AppCrash.  I really don't know where to go from here.  Any ideas on how to debug this type of error or where to go to learn how to debug this type of error would be very helpful.  Thanks!
A program created in VB6 is having problems with a few Vista computers.  Otherwise, it seems to work on Vista fine.  Upon double clicking the program icon, it will not open and Windows immediately says that a problem caused the program to stop working correctly.  Windows will close the program and notify you if a solution is available.

components not installed properly
your application could be referencing functions assuming from vb6 but ending up in using the same upgraded function in vista resulting in exceptiion.

can u try to install vb6 in the machine and try again?
