When I double click the Icon for the demo, the screen goes blank and then returns to the window with the scripts and what not listed. At the bottom of that screen it says something about an openGL error. What does that mean and can it be fixed???? Thanks.

You should try downloading the OpenGL drivers from, ummm, I forget the URL, whill post again when I remember it.

I downloaded some drivers from http://www.3dfx.com or you can try http://www.nvidia.com

Don't know if that's really what you need, but when I needed a OpenGl-driver for RTCW, I took it from the firstURl and it worked...

Notice that MoH needs a stronger card then RTCW, I thought it needed Texturing capability or something

I figured out the solution for the problem running the game (or demo) in XP with a
nivida chipset.
First:
Update to the latest Detonator drivers for your NVidia card for windows XP/2000.
( http://www.nvidia.com/view.asp?PAGE=windows2000)
Version 23.11

Second:
After the install of the videodriver search
for these 2 files:
opengl32.dll (670Kb, dated 7 sept 2001) and
opengl32.lib (325Kb, dated 16 july 1996).
The can be found in the windowssystem32
directory.

Third:
Copy these 2 files into the game dir
x:Program FilesEA GAMESMOHAA
(x is your drive letter where the game is installed!)
overwriting the old files that were there.
(the old opengl32.dll is 717Kb)

Last step:
Remove the '3dfxgl.dll' from your game dir.
that should fix the problem. I believe the
engine tries to load the 3dfx drivers
first. I think when they did the RTCW code
they did not do a validity check to make
sure there was not another opengl driver
before erroring out.

After these steps MOHAA will work on XP too!!

Have fun people!!
