I've written a straightforward .dll for a program that I use (VISSIM) and testing it on Win2000 succeeds, but when I try that under XP the program (VISSIM) won't accept the .dll.
I've programmed other .dll's that run on both systems, but this one doesn't work.
So I wanted to ask, what can be wrong with my code, so that XP doesn't accept it. (The XP-PC is a Dualcore and the Win2000 is singlecore)
