defiantly my first time to try rhino 8 and download installer and get a license key. then install/run, and enter email/license key, and show “expired” message; thought might be some issues unknown, then added another email and downloaded again with a new license key, and same thing happened - license expired. annoying for wasting hours to handle this for just to try this to see if it will meet with my expectation. now I give it up and to see if there are others alternates.
This usually happens if you had the evaluation version in the past.
That message says you’re obviously lying. Also if you think you’re going to get any pity points with your sob story about giving up, you’re mistaken.
