Invalid License Key test

Hey, opened a new account and tried several times to enter the license key. getting always the message that the key is invalid. don’t know what to do

Mmm :thinking: I think you’ve tried using Rhino with a new Evaluation license, anyway Mcneal has changed its way and So you can’t add another Evaluation license again

but this is the very first evaluation key i’ve tried to install. :man_shrugging:

then mmm Wait for Mcneal Guys to help u

Are you sure this is the first time you’ve tried to install a demo version? If so, for licensing issues it’s best to contact them directly at

Hi Kristina -

You downloaded an evaluation version of Rhino 7 for the first time on March 4th. You are only allowed a single 90-days evaluation period, after which you’ll need to purchase a license if you want to continue using Rhino. Note that if you are a student, you qualify for a 80% discount and can use the license after you are done studying.
