dacolem1: Also, it mentioned that Windows 7 was unavailable when the game was made, so compatibility isn't guaranteed. I ran this on Windows XP, so perhaps anyone that has run Witcher on Windows 7 could let us know how it runs.
I ran the Witcher on Windows 7 64-bit with no problems. I don't know about the Intel graphics though, it might not be poweful enough. Anyone else know?
I'm almost certain that if you do try to run the game with Intel graphics you'll get an error message saying you don't meet the minimum system requirements. Fortunately it's easy to bypass this error and get the game to run. A description of how to do this is in the sticky thread "Fixes To Common Problems".
