Hello all,

I am trying to open a TIA project and on install it tells me that I have an 'Installation Optional' for WinCC Comfort / Unified Comfort on V16. I have used the Step7 / WinCC V16 installation media to install the engineering system for WinCC V16 but after installation I still get the same message. For reference, this is a V17 project with a V16 WinCC instance. 

Closed cause question posted twice.

The second thread with the subject WinCC Comfort / Unified Installation Versions is published within the conference SIMATIC WinCC (TIA Portal)
