If deleting the stuff from the registry doesn't work or you're still getting uninstallation errors, one way that I used to get around it was to go into Safe Mode and run the setup.exe file from the disc.

Now you can install the game *Smile hopefully without getting crc problems. If the add/remove procedure results in an error - skip to the next step and continue as it will still remove the game with the remaining steps.Ģ.) After or If the uninstall finishes go to Start - Run - type regedit - hit Enter - click on the + sign next to HKEY_LOCAL_MACHINE, click on the + sign next to SOFTWARE, click on the + sign next to BETHESDA SOFTWORKS, right click on Oblivion (if it is still there) and then delete.ģ.)Now still in Regedit find HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ and delete it the same way you deleted oblivion in the last step.(If it is still there - this is the uninstall key for add\remove programs)ĥ.)Go into explorer find the C:\Program Files\Bethesda Softworks\Oblivion folder (if it is still there) and delete it.Ħ.)find the folder C:\Documents and Settings\USERNAME\My Games\Oblivion (Substitute your username for USERNAME) and delete it (Again if it is still there)īy doing this it will delete all traces of the game from your computer. To manage without having to reinstall windows, try it - at the best you'd save buying a new disk and at the worst it might not work and no harm would be done.ġ.) Go to Add/remove programs and uninstall Oblivion (If it shows on the list). It had happened to me personally and my disk is fine. The crc error is kind-of a developer's fault which happens if you install the game on a system where it had already been installed and uninstalled before.
