Help with Opengl

when i had windows 98 every thing worked fine for me but when i upgraded to win2k things started to happen. when i tried to install quake3 and tried to play it would not let me becaus it said could not load gl sub system. so i went to the site to and tried to down load it from there but it gave message about go here for new win drives. So i went here and down loaded the opengl95.exe, it said put these files in this folder but i not sure which one to put it in. So please can u tell me what to do when i want to install opengl on win2k and how to do it, and where to oput thoese files
