I have been able to play Halo 2 Vista on my Windows 7 OS and it worked fine last time I played it a few months ago. However, it just recently stopped working and everytime I try to launch it I get a "Halo 2 for Windows Vista has stopped working" error before the window even comes up. The game just flat out refuses to run, I tried compatibility mode and running as administrater but that wouldnt work. This problem happened really out of the blue and I dont know what I should do to fix it.

-Uninstall the game.


-OPTIONAL STEP - Download and run CCleaner to remove any excess junk/settings:

-Install the game.


-After installing the game and verifying the serial number go to the games installation directory and set startup.exe and halo2.exe to run as Administrator (Properties > Compatibility). This step helped me stop the profile download and updates stop repeating indefinitely on Win7.

@Kills Alone I tried what you suggested but I still get the error that "Halo 2 has stopped working" as soon as it tries to launch.

Also, how do other games work on your computer (recently, not weeks ago)?



And, what was updated/removed or modified (software or hardware) on your system recently?
