Now go to Users/?Your User Name?/Documents/My Games and delete the Oblivion folder, Now go to Users/?Your User Name?/AppData/Local and delete the Oblivion folder, Now go to Steam and under your game library right click Oblivion, go to manage, then Uninstall I recommend everyone do this, it will minimize any problems you may or may not have, Oblivion is a 5gb download, that should not take very long to download, just take the time to do it right from the start and when modding Oblivion you don't want the game in your program files directory, if you have never modded Oblivion before and you have the game in your Program Directory, just do the Clean Installīefore you start you need to delete all previous oblivion folders, especially if you have ever used mods before, they can be left over files you are unaware of that can cause serious hiccups, first open file explorer and go to what ever drive you have your game installed on, go to steam/steamapps/common and delete the Oblivion folder.
