The software works fine. but my experience with Apowersoft has been that their lifetime giveaway licenses stop working after a couple of months. They check the license online every time the software runs, and permanently disable the license if it ever fails to verify against their online database. They seem to drop giveaway licenses from that database regularly.
They make some of their functionality available free online though: https://www.apowersoft.com/free-online-screen-recorder
