Vista - any way to get Quake4 to work on VISTA64

Windows Vista Users: If you're having problems running this game under Windows Vista, first make sure that you're using the latest Vista graphics and audio drivers for your hardware, and the latest version of this game (see page 4 for patch details). Next, make sure you don't change your UAC settings after the game has been installed, as due to Virtualization this can change the location of the game files and settings. If you can't launch the game successfully when UAC is enabled, you will need to run the game with full Admin privileges. To do this either right-click on the launch icon and select 'Run as Administrator', or right-click on the launch icon, select Properties and under the Compatibility tab tick 'Run this program as an administrator' then click OK. I strongly recommend that you refer to the TweakGuides Tweaking Companion for Windows Vista for more information - in particular check the 'Gaming in Vista' section of the Graphics & Interface chapter; the UAC section of the PC Security chapter; and the 'Personal Folders' and 'Directory Junctions & Symbolic Links' sections of the Windows Explorer chapter. These will tell you how you can fix game-related issues and also explain the relevant differences of Vista.
