j´ai été confronté au même problème que toi et j´ai trouvé la solution ici:

Citation :A problem occurred initializing Direct3D. Hardware acceleration maybe disabled, please run DXDIAG. Halo could not correctly initialize the 3D portion of DirectX ( Direct3D) to display the game. DirectX may be corrupted or video Hardware Acceleration may have to be increased. For more information, visit the following Microsoft Web site:

Microsoft recommendation: This can occur if you are running a utility that forces your video solution to use a particular refresh rate when you run DirectX games. Examples of utilities like this would include, but are not limited to, PowerStrip, ReForce, NVTweak, NVHardPage and RivaTuner. Try to disable these utilities. For more information about how to disable these utilities see the page where you downloaded them. You may also be able to override these utilities by setting a customer refresh rate for Halo by using a Command Line Parameter.
Follow the instructions in the following article. For additional information about DirectX Corruption, click the following article number to view the article in the Microsoft Knowledge Base:

Donc si comme moi tu utilises un soft de tweak qui modifie la taux de rafraichossement désactive le et tu pourras profiter de cette démo.
