First try to do so with the Oracle Universal Installer. If that does not work then:
shutdown all Oracle related services and change them to disabled.
Remove the Oracle directory and all of its files and subdirectories. If you are blocked due to file locking remove all you can, reboot, and then remove the rest.
Remove the Oracle directory under PROGRAM FILES and all of its subdirectories and files.
Go into the registry and remove My Computer/HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE only if you know what you are doing.
If not, and you mess it up, I am not responsible so be very very careful. |
