Uninstalling SAP ASE

To remove SAP ASE, run the installer. The uninstallation process reverses only those actions originally performed by the installer, leaving intact any files or registry entries you created after the installation.

Prerequisites

Stop all services using the Services option from the Control Panel. If any of the services are marked to automatically start, change them to be started manually. Restart the system to release any DLLs that are already loaded into memory.

If you installed SAP ASE version 15.7 on top of an existing SAP ASE 12.5 or earlier, that earlier version of SAP ASE created a shortcut that launches the uninstaller, whereas SAP ASE 15.7 registered the uninstaller with the Add/Remove Programs option on the Control Panel. Use the Add/Remove Programs option to remove SAP ASE. This does not remove some of the shortcuts created by the SAP ASE version 12.5 or earlier installer; you must manually remove these shortcuts.

    Note: You may need to confirm the deletion of some files that have been modified since installation.

  6. Manually remove any files or registry entries you created after the installation.
