The game won't run on HP DV9535 laptops with Intel(R) Core (TM) 2 Duo processors with Nivida graphics cards 8600 GS, 2GB RAM and 1.5 Ghz processor. The DEMO version installs a driver AMDLLD.sys. As soon as you reboot, the system crashes with a blue screen. Which is no supprise as this is a INTEL machine. You need to delete the file in safe mode before rebooting the system. I wonder how a company can sell such a poorly developed product? I can't even return this lousy product as the "copy right" seal is broken.
