I was going to recommend this thread for instructions on what to do:

…but I see you're already posting there.
I didn't say "impossible" so stop misquoting me, I said "almost", and it is.
I have tried every known trick on the net to get it to run on my system with no luck. You say you played in on XP about 5 years ago so that means you played it before any of the service packs had been added, that might be the reason you were able to run it. I have talked to others who have tried to run it on WinXP+ SP2 and I haven't found a single person yet who got it to work properly.
There was one person over at Ironworks that was experiencing the same issue I was who finally got it to work by using a program called QEMU, which actually emulates an entirely different system on your computer. I downloaded it and gave it a try but couldn't quite figure out how to run it. I finally decided it just wasn't worth going through all that.
