Hello Coroleu
yes. You can do this.
Take a look at this explainer video. at my youtube channel: https://www.youtube.com/watch?v=WsE3-U6spec
Also, try it out. The basic free plugin has almost all features you need. That way you can first give it a try.
Hope this helps
In the video we see that you must be registered/logged in to apply the serials and download the file, can we avoid this? Because the purchase would be done once and the access to the download would be for a few students, we want to avoid that everyone is registered. Is it possible? Thank you.
