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