OpenGL v1.2 & 1.3 are included with the drivers for your OpenGL video cards. So you only need to make sure you have the latest OpenGL driver for your video card. If you do not have the latest driver with OpenGL 1.2 or 1.3 support, either use GLSetup (for Win95/98 only) or contact the video card manufacturer directly and ask them for an OpenGL 1.2/1.3 driver for your card and OS.
You will also need an OpenGL hardware driver for your particular 3D hardware accelerator board..
For consumer-level boards we strongly recommend running Glsetup to automatically download and install the latest & greatest video driver.
