hi there, i bought a imac 27" quad core i5, and like in my previous imac 20" i created a partition to play my games in bootcamp...but this time i installed the W7 64bit ( used the trick command promt on instalation to del c:\windows\system32\drivers\atikmdag.sys if im not mistaken, to get the screen to work and finnish the instalation ) did everything by the book, installed drivers from OS X dvd, then bootcamp 3.1. But all my games ( pes 2010, resident evil 5 and OF dragon rising) dont work! the only one that works is company of heroes ( 2006? ) PES 2010 installs but when start .exe gave me a message ( doesn't work on 64bit OS only 32bit ) the other 2 don-t even let me install them appearing the same message of incompatibility...so...i installed W7 32bit ultimate...now the messages didnt show, instead, a black window ( look like DOS ) appears and disappears in a sec, in PES after instalation, when trying to run the game, on the other 2, on the attempt to install the games just like in the 64bit version. So, i rolled back to what i thought it would work, since i know there are some issues with W7 and imac, the XP SP3! with same results on W7 32bit...pops a window like DOS, for a milisec, and disappears...over and over again...please HELP! thanks in advance!
