Just know that XP won't be supported for much longer. And I can verify that Sims 3 works on Win7 with no problems.
i havent tried yet the sims 3 cd. hope it will work. hehehehhe. but for CSI, totally cant play at all even i tried to make it as first reply ask me to do. also cant play it. i tried to put compatibility mode for xp service pack bla bla... still cannot. but during installation succeed. is it my cd broken? i dont think so cuz i still can download the cd to my notebook.
i shall update to you guys if i manage to solve this situation. thanks all
