Hi! Thanks for signing up.
Both the download link and the activation key parts are supposed to be hidden. The system was, that you had to wait for the next update (up to a few weeks, depending). Then you would receive an email with the new update for you to download.
But I want to change that soon, so people will get the download link right away.
Let’s do that for you right here. Here you go: https://animationpaper.com/download-pre-release/
Others reading this are welcome too!
After downloading and installing, when you run Animation Paper for the first time, you click the link in the small activation-key-window coming up. Following the link you register and get your free activation key. And you are all set.
