Now you run Oracle installer to install Oracle again, but the installer is saying that Oracle is installed and asks you whether you want to uninstall (deinstall) that.

  2. Now look for services with names containg ora or oracle.
  3. End those processes.
  • Delete Oracle installation folder.
  1. If you could not have deleted C:\oracle or D:\oracle or wherever you had installed Oracle previously and C:\Program files\Oracle, then try deleting that folder now.
  • Remove Oracle-related registry entries.
  1. Start --> Run --> type in regedit and hit OK.
  2. Delete the following keys (some may have slightly different names in your registry):
