It's the same thing as we found with WinXP; a few people had no problems running the MM games, most needed to upgrade to v1.2 of the game and then apply Mok's patch, and there were an unlucky few where even this did not help. It depends on your system and how it interacts with your chip. Our experience suggests that no two setups are exactly the same.There are separate Mok's patches for MM6, MM7, and MM8. The link to the MM6 patch is given below; the next two posts give the MM7 and MM8 patches respectively.
BDJ's modification of MM7 does not require Mok's patch.
