at last it works perfectly........

1.Installed Daemon tools 4.0 mounted images, installed game with serial.
2.right mouse button on My Computer selected manage and then device manager disabled secondary IDE ATA/ATAPI controller
3.open DT4, make all emulation options on and exit. Leave all emulation options ON!
4.play the game

and do NOT patch image or anything.
i am playing now, it is a beautiful game and i think this works for Chaos Theory
