How to clear registry and do a clean OBIEE Uninstallation

Hi friends..I will be discussing how to uninstall OBIEE so that we can do a fresh install


1.       Go to Start –> Control Panel –> Select Oracle Weblogic and click Uninstall/Change

2.       A popup window will open, just follow the below screenshots


3.       Go to Start –> All Programs –> Oracle Business Intelligence –> Deinstall

4.       A popup window will open to deinstall business intelligence tools. Follow the below screenshots


To deinstall Oracle Database XE by using Add or Remove Programs:
  1. In the Windows Control Panel, select Add or Remove Programs.
  2. Select Oracle Database 11g Express Edition.
  3. Click Change/Remove.
  4. In the Oracle Database 11g Express Edition - Install Wizard, select Remove, click Next, and then click Yes in the confirmation window. When the deinstallation completes, click Finish.


1.Go to Run and type regedit. The Registry Editor window appears.

2.Navigate to the locations inside HKEY_LOCAL_MACHINE shown in the screenshot and delete the marked folders.

Deleting the below folder KEY_OH29480770 cleans up the OBIEE installation from registry.

 Deleting the below folder KEY_OH2023886701 cleans up the Weblogic installation from the registry.

Navigate to the services folder as shown below

Inside the services folder navigate to the folder OracleServicesXE and delete that folder.This cleans up the database from the registry

Now uninstallaton is complete. Your system is ready for a new installation. Restart the system and start the fresh installation.

Some interesting discussion on uninstalling Oracle database completely by cleaning up the registry and also on things to take care when installing database on servers.

Till next time..bye :)


  1. Do you have any comment on Dropping the OBIEE system database? Is this required? pros/cons of keeping it and only resinstalling OBIEE SOFTWARE AND TOOLS? Thanks in advance

  2. I want to uninstall only OBIEE 10g but not oracle database , so uninstallation of oracle weblogic and oracle database are necessary?

  3. Hi I am trying to uninstall OBIEE 11g.
    I am getting below error
