Post-upgrade from InTouch HMI 2017 U3 SP1 to InTouch HMI 2020 R2 SP1, the following warning message is logged in the LogViewer:

“Unable to start the aaServiceHost Could not load file or assembly 'PCS.Client.Discovery, Version=1.3.1.0, Culture=neutral, PublicKeyToken=23106a86e706d0ae' or one of its dependencies. The system cannot find the file specified.”

This has no functional impact. However, restarting the system will resolve the message.
