Troubleshooting Uninstallation

Uninstallation is usually straightforward when the previous installation instructions have been followed correctly. This topic describes how to recover from a failed uninstallation.

Recovering from a Failed Uninstallation

For server-based Siebel products, if you encounter any issue with the uninstallation process, you can run the uninstallation again. Doing so uses the backup made by the uninstaller under the backup directory (ses_BAK, for Siebel Enterprise Server) to reconstruct your original installation. You can then address the cause of the failure and run the uninstallation for a third time to complete the uninstallation process.

NOTE:  The recovery mechanism can be used only if the uninstallation process fails. It cannot be used to undo a successful uninstallation.

Full Uninstall Options on Microsoft Windows

Server-based Siebel products on Microsoft Windows platforms, including Siebel Enterprise Server and Siebel Web Server Extension, all have a "full uninstall" option available in the Add or Remove Programs panel. If, for whatever reason, you have installed multiple instances of the same product on the same machine, then only a single "full uninstall" option may be available, corresponding to the most recently installed software instance.

If you want to uninstall a product instance but the "full uninstall" option is not available for this purpose, use the uninstaller.exe option instead, which is specific to each installed instance.
