[SOLVED] "opengl32.dll already exists" error, MOH Allied Assault, Win 11

Hi all

Been going round and round with an issue all night and have reached a dead end - help!Game is Medal Of Honor Allied Assault Warchest from GOG. I had the game running perfectly with ReShade. Then I foolishly added the game to Nvidia GeForce Experience (yes, I know, it sucks) to try some rescaling, after which the game refused to load past the little dialog box, a grey or black screen and then back to desktop.

I have now removed GeForce Experience, and after uninstalling ReShade from the game AND uninstalling and re-installing the game, I was able to get the game to load by itself by adding an OpenGL32.dll file in the game's root folder, which seems to have been missing altogether. I used the one provided by GOG. However, problem is, when I then try and re-install ReShade to the game, to it, I get this :



Now, to fix this I can remove the default generic opengl32.dll (that I added earlier) out of the root folder, ReShade then completes the install the next time I try and installs its own opengl32.dll (Corsire's injector). But the game now goes to a black screen and shuts down back to desktop when I try to launch it. If I put the original opengl32.dll from GOG back (replacing the ReShade one) it loads perfectly again, but without ReShade at all.

Anyone got any clue as to what can be done? Just wanna play MOHHA with the iMMERSION shaders! If it helps, I was able to grab the dialog box as it loads:



And this is all that is in the LOG file:

 The game clearly natively needs opengl32.dll to launch, but for some reason now it refuses to accept the ReShade version of it, even though it was fine before - but I can't give it both! I am not very savvy about this stuff so please explain stuff like I am a five year old (lol)

Thank you for your lovely help! 

You could just leave it there and inject ReShade externally, see www.pcgamingwiki.com/wiki/ReShade#UWP_Games .

Okay, many thanks fella, I shall give that a try
