I have installed free edition of unity. but i am not able to find the license key used. where to find it?
Do Help->About or Unity->About and you'll see most of the serial number. Why do you need to know the serial number?
I'm experiencing the same issue trying to use the free individual edition, I downloaded and installed unity hub and it is requiring a license to activate. where would I get a license key for manual activation or check for one that I may already have? I used to use unity 3d a in 2017 but it was the free edition as well. I'm uploading a screenshot of what I'm looking at. Also did I somehow download and install the incorrect version of unity?
