does anyone know how to manually remove previous versions of opengl ???
Any suggestions are greatly needed
As far as I have been able to find out over the past few days, the key file for OpenGL on Windows hasn’t changed in years. The file is Opengl32.dll and it is file upon which all the different opengl drivers depend in order to work with Windows.
Now, that said, the different versions of drivers for specific cards (3dfxvgl, nvopengl, etc.) can be removed by setting the video display to VGA and installing the default Windows VGA drivers. Then a clean install of new drivers can be made.
