Hi. I recently bought a retail copy of Halo 2, but it won't install on my computer. I'm running Windows 7 Professional (build 7600 i think..). I can install Map Editor, and The dedicated Server app. but when i try to install the game I get some sort of error: "redists/vcredits.msi: The installation is forbidden by system policy. Contact your system administrator." I have googled and found people with similar problems, both in connection with Halo 2 and other programs, but have not found a solution that works for me. I am the only user of this computer and I am the admin. I have tried to right-click and use run as admin but it makes no difference. I have also copied the disc to a folder on my machine but i get the same error wen trying to install from the folder. I also tried this and similar actions within the the Local Security Policy settings:
"Click Start -> Control Panel
Open Administrative Tools
Open Local Security Settings
Click Software Restriction Policies
If no software restrictions are defined, right click the Software Restriction Policies node and select New Software Restriction Policy
Double click Enforcement
Select "All users except local administrators"
Reboot the machine "
I have tested all the Compability modes, and that did not work either. Does anyone know whats wrong? I know people have trouble playing online, due to an issue with the Windows Live service but the game usually installs just fine.
Some links I have visited, regarding the problem: Forbidden by system policy Halo 2 wont install on Vista
