Uninstall manually on Windows

If the uninstallation program is not present or an aborted installation did not create a complete and functional uninstallation program, you can manually uninstall WebSphere Portal.

To manually uninstall WebSphere Portal:

1. Run the stopServer.bat WebSphere_Portal -username admin_userid -password foo task, from the WP_PROFILE/bin directory, to stop the WebSphere_Portal server.

2. Verify that there are no other installations or uninstallations running.

3. Locate and delete the portalinstall.lockfile file, if present, located in the %TEMP% directory; for example,C:/Documents and Settings/Administrator/Local Settings/Temp/portalinstall.lockfile.
   The Portal installer creates the portalinstall.lockfile to prevent two installations or uninstallations from running simultaneously. This is a temporary file and ordinarily gets deleted when the installation or uninstallation successfully completes, but it may not get deleted during an aborted or crashed procedure. Until this file is deleted, it will not be possible to initiate another installation.

4. Uninstall WAS; if you need to manually uninstall it, refer to Uninstall manually.

5. To edit the vpd.properties file, located in the %SystemRoot% or %USERPROFILE% directory, and remove WebSphere Portal information:

   1. Open the vpd.properties file.

   2. Remove all lines that contain the $PORTAL_HOME installation string.

   3. Save and close the vpd.properties file.

6. To edit the .ITLMRegistry file, located in the %SystemRoot% or %USERPROFILE% directory of the login ID used to install WebSphere Portal, and remove WebSphere Portal information:

   1. Open the .ITLMRegistry file.

   2. Remove all lines that contain the $PORTAL_HOME installation string.

   3. Save and close the .ITLMRegistry file.

7. To remove WebSphere Portal entries from OS's native registry using the native registry tool:

   1. Read the Windows™ help system for information about using the Windows Registry Editor.

      When editing the Windows registry, computer may not function properly if you delete the wrong information. If this happens, see the Windows Help system for information on how to restore the registry.

   2. Click Start -> Run and then type regedit to start the Windows Registry Editor.

   3. Delete all entries under the HKEY_CURRENT_USER -> SOFTWARE -> IBM -> WebSphere Portal Server.

   4. Run the sc delete service_name from a command prompt to remove a Windows service from the Services list and registry. Click Start -> Control Panel -> Administration Tools -> Services to view the WebSphere Portal services names.

8. Delete the $PORTAL_HOME directory tree and the WP_PROFILE directory tree.
