Fezero had a post on their website that said they don't do comapatibility for vista. So if it happens to work great, if not then they're not doing anything to fix it. They also have no support for 64bit systems, but it seems to run fine on them. When I tried to run it in vista, it said something and specifically mentioned my OS, which was vista. So I ended up installing windows xp and dual booting. Be careful if you do that though because windows has a bad habit of erasing the mbr and overwriting it with its own.
