Purchase Sharing of Logic Pro is not working properly for installed app

I purchased Logic Pro with a one-time purchase and I have my apple account shared with my family. I'm trying to install it on my wife's computer using the shared from "my name" in the app store. It installs fine, but doesn't recognize the license when it starts. It just asks if I want to start a trial. I've tried doing a hundred different things to wipe it from her system and reinstall from the app store "shared from me" select box. Same result every time. I'm so frustrated because I'm supposed to be able to install this on my families computer.
