If you have already installed Oracle software, use Oracle Database Configuration Assistant to delete all current instances. Make sure that the necessary services are started in Control Panel Services before doing this.
2. Stop all Oracle-related services in the Services control panel.
3. Deinstall all Oracle products, using the appropriate installers.
4. Delete all Oracle software directories, including the inventory files in the C:\PROGRAM FILES\ORACLE directory.
