Hi Savaged95 and welcome to PCHF
Take a look at this:
First thing I did was install the 169.01_forceware_winvista_32bit_english_beta driver released specially for the demo. The initial install went smoothly, except for not creating any shortcut. I found the Crysis.exe and created my own. Now the real problems started. Clicking on Crysis.exe popped up an error message saying intellaptopgaming.dll was not found. I checked the crytek directory and saw it there. I reran the setup with admin privileges and nothing. I copied the dll manually to system32 and registered it, and rebooted, still nothing. Then I found the solution, in the same bin32 directory where the crysis.exe is located, run the fxc.exe program and that fixed everything. Weird? yes. You must click fxc.exe first each time you want to run the demo.
