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?
-wim

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

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

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

Thanks Steve, I had a repeated command in another folder
