hi

yes, g2 will work with windows xp. this is what I am using and it installed and is running with no problem. have read where some have had a problem with installation but this seems to be with certain cd-rom having problems with the protection scheme they use to prevent the cd from being copied and not a problem with windows xp.

also I have added add-ons 1, 2 and 3 with no problem

good luck
joe
