I can not use my free trial

Hi,

I tried using the 90 day evaluation but it says my evaluation has expired before I even started using it what do i do?

Perhaps these threads are relevant to your situation:

The TLDR; of the previous reply is: you already had a free evaluation starting April this year. You get to get only one.

If you want to continue using Rhino you need to buy a license - check Rhino - Buy - Rhinoceros . Note that if you are elligable as a student you can get the license for a big discount. This license can be used for commercial work as well, even after you graduate.

i didn’t receive the license key what should i do ?

Hi Ayesha, the key is shown when you enter in your email, return to the original page to start the evaluation and enter your email again.
