You obviously know nothing about computers and programs. First, they don't make it for mac (windows and mac use different systems so they use different programs) so .exe's doesn't work on macs. /thread.

If you have leopard and a dual prossecor like on the new mac books you can have both xp and leopard all you need to do is buy a copy of xp and make sure you have bootcamp. It should explain rest of instalation , then restart comp it will ask if you want leopard or windows choose windows then download it your set. i beleive this works but have not done it myself
