Opengl32.dll re-installation

I recently installed Escape from Monkey Island and when I try to play it, it gets an error saying that my C:\WINDOWS\SYSTEM\opengl32.dll appears to be corrupt, try reinstalling it. What’s going on how do I reinstall the file. Please Help!

Look for the file on your Windows install disks or cd and copy it to your c:/windows/system directory. It’s easy to do from your WINDOWS EXPLORER program. I would first move the old file to the temp directory, then copy the new one to the c:/windows /system directory that way if it doesn’t work you can always move the old one back
