Error 0xc0150002 when opening Halo 2

Ever since I got windows vista ultimate, whenever I open Halo 2 i says
The application failed to initialize properly (0xc0150002). Click OK to terminate the application. Got any ideas to solve it.
Answer #1
Most of the problems I found that produce this error are related to Office.
Translation:
There are two possibilities here, both of them a bit convoluted. In the first scenario, sometime after installing Office 2003 and Windows XP SP1a (Service Pack 1a ) on your computer, you either upgraded WinXP Home to WinXP Professional, reinstalled WinXP, or repaired WinXP. After doing this you can’t start an Office 2003 application without getting this error message. The second possibility is that, sometime after installing Office 2003, you installed WinXP SP1 (Service Pack 1) and did not restart the computer as prompted at the end of the SP1 installation process. (This is a common oversight. The Restart Your Computer request is often buried under other windows and dialog boxes displayed during the SP1 installation, and many people miss it.)
Solution:
In the first case, reinstall WinXP SP1a. The easiest way to do this is to visit the official Windows XP Service Pack 1a Web page at www.microsoft.com/windowsxp/pro
/downloads/servicepacks/sp1/default.asp and follow the instructions there. For the second scenario, restart your computer. You should be able to restart your Office 2003 applications without incident.

Answer #4
Sorry mate, I can’t find anything relating to the error you’re encountering with Halo 2 and Vista.
I guess all I can say is to try updating to the latest drivers for video card, and running Windows Update.
