Uninstalling and Installing new drivers

[TRDLE]

I have display and direct draw drivers ver.4.11.01, and Power desk driver ver. 5.11.012. In the procedures on uninstalling drivers they refer to an uninstall feature in Powerdesk that I do not have. Can someone give me some clues on how to easily replace my drivers? Can't I just install over my current drivers?
