MK3 connection to Controller Editor

Hello

I am trying in vain to connect to my S61 MK3 keyboard via the Controller Editor. On a Windows 11 machine, and nothing else running, "connect" is grayed out. I'm a bit stuck here. The real reason why I am trying to get the editor up and running is that I would like to create a banner image on a midi template as described in the Release Notes on the last Hardware Connection update? Not that it's terribly important, it could just be fun.

Kind regards
