halo 2 running on xp

OK, listen up... Halo 2 a great game, officially only running on Vista... does run on xp, too. A friend of mine and I just found a little workaround. If you'd just try to install Halo 2 on xp the installer crashes with an error message. U can bypass this by using a tool, found on noumerous torrent sites. Here is a little screen of the installation process. Halo 2 currently only runs in campaign mode only, we are (right now) tryin to figure out a way to play it via lan, too.
