Summary

Use Requiem, Avenging Angel CD to install game under default directory (C:PROGRAM FILES). Download all patches for Requiem, Avenging Angel (ReqUpdate.exe, req_1_2.exe, rqd3d13.exe, rqsfw13.exe) and place into created directory (C:Program Files3DORequiem). Now, take this *entire* 3DO directory and place in XP's DESKTOP, MY DOCUMENTS directory. Start the patches in this order: ReqUpdate.exe, req_1_2.exe, rqd3d13.exe, rqsfw13.exe. All patches should (must!) work successfully. Now, place entire 3DO directory back under C:PROGRAM FILES directory. Copy D3D.EXE file that is already in the C:Program Files3DORequiem directory and place into "root" C: directory of your computer. Double click on Requiem.exe in C:Program Files3DORequiem. Program should now start, and with full hardware video support. This worked for me, so it should work for you -- but no guaranties!!

I can't seem to find any patches for requiem... the 3d0 site is down and most of the sites that had it took it off line

When I try to install it under XP SP2 the setup loads until 100% and then it stops and nothing happens. The setup window stays open but freezes at 100%.

Running Setup will stop at 99%. Can i find a patch for this or u may give me some instructions to bypass this error.
Can't install 3DO Requiem Avenging Angel on my Windows Vista 32bit !

While it is possible to run this game in Windows XP using some esoteric install tricks, the game itself does not run perfectly.

Namely, certain triggers do not activate during single-player (i.e. some doors will not open when they're supposed to), preventing you from playing through the game normally. You can still play through about 80% of the game (including the final level and end boss), but you have to use a level skip cheat to get past sections that aren't working due to the triggering issue.
