A question probably asked a million times - uninstalling drives after updating

I have just updated my Alcohol 120% to the latest version. After the installation i have one virtula drive more, which is recognised as a normal drive by the computer [previously it was a virtual one]. The new Alcohol has set another virtual drive, so one is enough for me. What can i do to uninstall the previous one completely? [uninstalling the drive in computer panel doesnt help, it comes back after the restart]. Thanks for help.

Did you try to remove the old version before installing the update?
