Insert the game cd and browse the folders. Navigate to the folder that stores the setup.exe. It is necessary that you do not use the Launch.exe.
Perform a right click on the setup.exe and choose properties. Switch to compatibility Tab and click "edit setting for all users".
Choose "Windows XP Service Pack 2" in the dropdown field and check the box "Run program as administrator". Save this settings.
Start the Setup.exe (not the Launch) file by double-click. Finish the installation. Start the game and navigate to options.
In graphic settings set the "Bump mapping Quality" to low. Save this settings. If it's needed, restart the game.
Now you can play.
