    How to Clear the List of Oracle Client Homes install on a User Machine...

    Hi.

    We had a PC that had Oracle Client 8.0.5 and 8.1.7 installed in Default_Home
    (c:\orant) and Default_Home1 (c:\oracle).

    A third party package, installed certain components of Oracle Client 9.0.2
    in another Oracle Home which it called ora92 (c:\oracle\ora9 2).

    Since we no longer need Clients 8.0.5 and 8.1.7, I decided to uninstall all
    Oracle clients and install Oracle client 9.0.2. I used Oracle installer to
    remove as many things as I could. Then, I used Microsoft Explorer to delete
    various Oracle directories. Finally, I opened Registry Editor and located
    HKEY_LOCAL_MACH INE.Software.Or acle and deleted that. I rebooted the
    machine, inserted the Client CD 9.0.2 and ran the setup.

    However, when I try to specify the destination Oracle home to install the
    program to, the drop down still appears to have the definition for
    Default_Home, Default_Home1, and Ora92 and their previously associated
    directories in there! Worse yet, it somehow automatically creates all those
    directories (c:\orant, c:\oracle, c:\oracle\ora92 ) and an "inventory"
    directory under them! How do I get ride of all of those Oracle Home
    definitions, so I can install Oracle Client from scratch? Where does Oracle
    keep this list of former Oracle Home / Directory combinations?

    Thanks

      Hi John,
      You will have to remove the entries of ORACLE_HOME from the registry.
      This has to be done with care.
      You will have to delete some entries from Windows Registry

      HKEY_LOCAL_MACH INE\SYSTEM\Cont rolSet001\Servi ces\OracleServi ceORCL\
      HKEY_LOCAL_MACH INE\SOFTWARE\OR ACLE\

      Go to each of the above and look which values and keys you have to delete.

          I do not have the note id or title but I have seen an Oracle support
          note available on metalink that lists the steps to manually clean up
          the Windows registry so that a re-install will run cleanly. If
          Deven's advice does not fix the problem the note may be worth
          searching for.
