Hi there!
Thanks for bringing up this important topic. At the moment, unfortunately we do not have any automatic method for setting up 100+ licenses. This is on our todo-list though.
Also important to know: If you use the same activation key for multiple installs, Animation Paper will think it has been moved each time the latest install is run. Therefore the previous installs will ask you for a key again next time they are run. You can keep pasting in the same key, but definitely not an ideal situation. (Normally you only submit the activation key once).
Let me see if I can come up with some kind of helpful solution to your current challenge. I’ll get back to you asap.
Thanks,
Niels
