Key for test period

Good morning! I tried to download version for testing period today, the license key was sent to me, but it is not valid. I repeated attempts to get a valid code 3 times and have got 3 different emails with codes but neither of them work or appear in my account information. How can i get my trial period?

Please see numerous recent posts about trial licenses. It’s time to buy!

What you’ll find out from the search is that your evaluation period has ended. You get only one, any attempt to get more is not allowed.

If you want to continue using Rhino I invite you to visit Rhino - Buy - Rhinoceros and acquire a full license. Note that if you are a student you could be eligible for a big discout. Check the page for information on that. Educational licenses give you the same access to Rhino as full licenses and are forever. You can keep using that license commercially even after you graduate.
