I have tried everything suggested on the GfW:L forums, the Microsoft support forums, and Google. No matter what I do, Halo 2 will not run on my OS (Win 7 64). Is there any chance whatsoever that there is some developer secret that could make it run? I would love to be able to play multiplayer again just once before the 15th, but as it stands I'm left without a working copy of Halo 2 and have been since I upgraded to Windows 7. This is my last effort before I just hang the disk from my rear view mirror, if there's a dev out there who can help with this, or at least just tell me they can't, it would be awesome to hear from you.
