Unfortunately, it is not possible to activate the license automatically (see attached license request png). When trying, the program ask for a computer key???
Further when starting Rhino a command manager window pops up (see attached commandmanager.png).
So I don't know what to do next.
That could be your firewall are blocking the conexion with our server. The other problem you can solve it uninstalling Clayoo, but be sure that in the program list in (control panel > programs and features) Clayoo is removed.
