Rhinoceros 5 Error: “Command did not register”

Hello, I got an error when starting Rhinoceros 5 (64-bits). Once ignored the message by clicking “Ok”, the program starts normally but every time I start Rhinoceros the message come up… I know this error has already several times been reported on this forum, but with version 6

Rhinocheros Version 5 SR14 64-bit
(5.14.522.8390, 22/05/2017)


And why the “CopiaMassivo” command and not other ?

Hi Gustavo - As far as I know, CopiaMassivo is not a native Rhino command. Do you know which plug-in provides this command?

Yes, of course, this belongs to a plugin developed by myself.

In that case, I’m moving this thread to the Developer category…

Do you have multiple commands in your project with either the same name or uuid? That is one way for command registration to fail.
