I've downloaded Maya 2014 trial, when I run it, it says my license key has not been activated, and requests a key. But obviously it's a trial, so I don't have one. I see nowhere that I can click to tell it I want to run in trial mode.
What am I missing?
Sounds like to me that your trial is expired, actually. Sometimes problems like this happen. 😞
To my knowledge this cannot be corrected unless Autodesk knows of another way. You can always install the trial on another PC though.
I've never run a trial on this PC before, and this is a fresh Windows 8.1 installation. Is Autodesk able to provide support for installation of trials? Who would I contact? Very hard to pull the trigger on a purchase when you can't even install it.
