Virtual Prime does not connect to CK

[DG7RBN]

Hi Tschumi,
I'm not familiar with Win10. Using Linux for every day work, only forced to Win10 because Tim W.'s work on a Virtual Prime under Linux is not continued.
Tried to locate anything like "bonjour" or "mDns services" in Win10 settings and task manager. No luck :-(
So please be a bit more explicit with "turn it on and try again" ;-)
Thanks
Andreas

P.S. I have already reinstalled both HP Prime related programs.
