Part 2 - Installing BF2
1. Disable UAC if on Vista/7 and reboot your PC.
2. Insert BF2 DVD, close anything that auto runs and then view contents of DVD, right click Setup.exe and select Run as Admin. Notice you do not get prompted to confirm Admin Rights as UAC is turned off.
3. Follow installation instructions to install BF2, if our installation appears to hang after setting up the VoIP settings and before the installation of Gamespy, open the task manager->processes, find BF2VoiceSetup.exe, right click and select end process - NOT END PROCESS TREE!
4. Reboot to finish installation of BF2.
