Windows cloud zoo licensing- how to fix when it misbehaves

Rhino Rhino for Windows
1

In rare occasions with Rhino v6 (and even rarer in v7) you may encounter a cloud zoo (rhino account) licensing loop that says something like “rhino needs a license, please enter your email” which you will do, and see “license found! log in with (your name)” which you do, and that takes you your rhino account, which asks you to login and allow access, then says "login successful " go back to rhino-

when leads you back to rhino which says “rhino needs a license”

and then you use grown up words and throw your keyboard across the room…

good news! There are two fixes for this. One easy, and one slightly more advanced easy…

Easy method-
when rhino pops up the dialog asking for your email, look in the lower left and click options.

-click remove license
-rhino will close.
-re-lauch rhino and that same dialog should pop up.
-enter your email and click next
-rhino should find your license
-login to your account and click allow.
-go back to Rhino and wait a few seconds, rhino should launch this time.

If that fails, the more advanced method is:

  • close rhino and go to this folder in a file browser

%appdata%\McNeel\Rhinoceros\6.0\License Manager\Licenses

-clear the contents of the folder but KEEP the folder.
-empty your trash.
-restart rhino, and enter your email and login as prompted.

rhino should start as expected.

notes-
-this link points you to a v6 folder, this is correct even if you have v7, or the wip v8.
-please let us know if these fixes do not fix your licensing loop, as we need to help you because something weird is now happening.
-as always, if you can’t sort a rhino problem quickly with a forum or google search, please hit us up at tech@mcneel.com or call 206-545-6877

happy modeling!

I occasionally get messages from my clients about a different problem - like the one I just got a few hours ago:

(Translated from French)
It happens sometimes when have many Rhino files open and I try to open a new one: I get the message “Retrieving license from the manager”, but it doesn’t find the license. At this moment it is impossible to open another instance of Rhino, I try to close the dialog, it asks me for my email address and password to connect, I try entering that but it does not work.

The only remedy I have found is to close all my open Rhino files and then it works again… There are even times - like today - when I have to completely restart my computer…

Don’t know if it’s related, but this is not the first time I have heard of this happening.

I’ve heard of a few reports of that too, and could never duplicate it myself. I’m pretty sure it is a completely different issue.

I am as well, but as it also falls under the heading of ‘fixing licensing that is misbehaving’, I thought it was appropriate to post it here.
