How to use GLsetup in windows XP professional

Recently I bought a game pack (5 games) that uses glsetup. The read me file says that the games work under windows XP, but when I try to install GLsetup, It pops a message saying the OS is not supported.

Please, I need some advice or any information about this

You don’t need GLSetup. OpenGL support is delivered with the drivers for your video card, and GLSetup just attempts to make that process easier by downloading and installing the latest drivers for your detected hardware. Make sure you have the latest drivers for your video card correctly installed, and things should be fine.
