I just purchased Rhino6, but the licensing number was never emailed to me so I can’t use the program. Is there any way it can be emailed to me?
How did you buy your license? From McNeel directly or from a reseller? If McNeel, contact firstname.lastname@example.org, you will likely receive an answer Monday. If you bought it from a reseller, contact them.
Oh, and just in case it’s an educational license - you didn’t specify - if you ordered it online, they may not send you the license before they verify your status document - also Monday most likely.
