Vista - Halo 2 Failed to Initialize.

I recently got Halo 2,and before I had I had ran a test and it said I met the minimum requirements. When I tried to install it however, it would change my resolution to 800 x 600, the display the message-(Initialization failed.Either insufficient system resources were found to run the game or game data is missing or damaged.Reinstalling the game may fix this problem. When I also try to customize game install,it tells me-Installation cannot be customized after game installation is initialized. I looked at some other threads and tried to update my graphics driver,but it said I had a custom driver installed and trying to install another driver may damage it...WHAT SHOULD I DO?

Here are my specs-

Lol,thats it...PLEASE HELP ME,I WASTED MONEY ON THIS GAME.

Hello Madandfrustrate,
Have you tried to re-install the game as administrator ?.

No,how do you do that?

Open the DVD, (My computer, right click the DVD, explore), right click the install exe and go to properties and open the compatibility tab check the run as administrator box (at the bottom), press apply and install.

Ah,doesn't work.

Halo 2 requires a system rating of 5.0. Your graphics card is too weak to run it.

Thanks Frostmourne,I found that out earlier though when I ran a test on "can you run it". I think I'll upgrade to a 9500GT(I'm kinda short of cash.).Is a 9500GT good enough,or do you recommend any other cards?
