Halo On Windows Vista

Hello!I have another problem.I am with Windows Vista SP1 and when i start  Halo 2 it says :
Initialization failed.Either insufficient system resourses were found to run the game,or game data is missing or damaged.Reinstalling the game may fix the problem.

I have the latest update.

Any ideas ?

Sorry for my bad English.

Perhaps make sure you are running as an administrator.  You can right click the icon, and in one of the settings, check mark to run as admin.  This will give rights to memory and process use to Halo 2.
