Trial installation

Hello! Dont know if this is the right place to ask.

I just downloaded Rhino for mac with the intention to use the trial version before i decide to buy.
But the installer keeps asking me for license keys? How can i activate trial mode?

You should have received an e-mail with an evaluation license key - sent to the address you put in when you downloaded the program. If it didn’t come in, check your spam box. If still not, try re-starting the download and see if you get a new mail. Otherwise, you need to contact to figure out why the mail with the key is not being sent/received.
