TopView can be set to automatically launch at Windows start up by configuring a Windows Service to run a TopView Engine.
TopView Configurator provides tooling to easily set this up. In the TopView Configurator, open the configuration you want launched at start up, then navigate to "Configure Services" in the left sidebar where you can install TopView as a Windows Service.
For Remote OPC Classic, it is important to set the correct account for the service to facilitate OPC communication.
