Hey bddl,

Well if you have a dual boot Vista/XP computer you can boot into XP and install the program and use it there. If not you can also try using compatibility mode. First make sure you are an admin then right click on the app and then go to properties go to the compatibility tab and check Run this program in compatibility mode for Windows XP. Usually most applications will still not work even if it is being run in compatibility mode, so the best thing to do is either use XP itself or perhaps a VM if its a small light-weight application.
