    Disinstall Oracle Express XE

    lory
      Hi,

      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?

      Thanks and Regards
      Laura

            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.

                Installation guide, for Windows, has a section on deinstalling:

                XE does not use OUI or Inventory for installations, so no wonder OUI can't see it.

                  Note that op is asking about XE, to which OUI does not apply (so much for the U in OUI).
