Here is a solution: You need to open Program Files/Clayoo Beta 1.0/Clayoo.rhp with required version of Rino.
So, after Rhino opening, Clayoo menu appears in it's usual place.
It works now. Here is the complete way to activate clayoo in the case of it does'nt automaticaaly set at work.
Launch Rhino 5.
Go to tools / options / plugins
Than click the install button
Go to c:programs / clayoo beta 1.0
It immediatly launches the start window of clayoo for registration.
The best would that it automatically should work!!
