Uninstall AVEVA Real-Time System

Before you uninstall AVEVA Real-Time System (RTS), please ensure the following:

• No RTS server is running

• No ScriptHost process is running

• No RtsWebUI process is running

The recommended uninstallation process depends on your operating system (OS).

For Windows desktop OSs, we recommend that you use the Windows Control Panel.

For Windows Server OSs, we recommend that you use the original executable (.exe) file that you used to install RTS. If you don't have access to the original .exe file, you can still uninstall RTS by using Command Prompt with administrator rights and the Windows Apps & features system settings.
