I have it installed and running well on a Win10 computer. This winCC reads variables from seven different Siemens PLCs. I tryed to install a third part software to read OPC DA server, but this server is not running. I run the installer again, and installed the OPC XML gateway, but the server is not UP yet. What can I do to solve it?

The WinCC Professional should be able to run both.
