I've got a Win11 Tower PC that is used to controll the Virtual Win10 one:
Win11 Controll PC:
Version 23H2 (Build: 22631.4169)
Multiplicity 3.6 Build 00105.km
Virtual Win 10:
Version 1703 (Build 15063.483)
Multiplicity 3.6 Build 00105
Maybe thats a to big gap already - I can set up a Windows 11 VM tomorrow as well
