Uninstall all Oracle components using the Oracle Universal Installer (OUI).
Run regedit.exe and delete the HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE key. This contains registry entires for all Oracle products.
Delete any references to Oracle services left behind in the following part of the registry (HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Ora*). It should be pretty obvious which ones relate to Oracle.
Reboot your machine.
Delete the "C:\Oracle" directory, or whatever directory is your ORACLE_BASE.
Delete the "C:\Program Files\Oracle" directory.
Empty the contents of your "C:\temp" directory.
Empty your recycle bin.
I've installed Oracle Express XE on my windows 7 - 64bit machine where there is also the DB 11g.
Now there are some conflicts so I can't use nor XE neither the other DB.
I've launched the OUI but I can't see the XE OracleHome .
Do you know how can disinstall it, please?
