"Ultimately, it is the responsibility of Microsoft and/or specific hardware manufacturer to provide for backward compatibility with Windows XP; this is to insure that the device drivers are compatible.
At this time we do not have plans to change our older titles to make them Windows XP compatible for the reasons above. We realize this may be a problem for some users. If you have Windows XP on your machine, and the game will not function, your best course of action may be to return the game to the place of purchase."
