I have a voodoo3 card and have recently installed Windows Xp. I tried to install OpenGL with the Voodoo3 disk I have however windows will not open the disk up. Not with Autorun or even by running the setup.

What should I do?

That CD for your Voodoo3 is much older than Windows XP, so there is no chance it will have a driver for you. I’m also fairly sure windows XP doesn’t ship with OpenGL support for a Voodoo3.

Good luck.
