I have just finished working on the desktop app that I want to start selling on Microsoft app store. I am not sure on the licensing part. I want to implement a solution where when one downloads the app he pays via the store,and if he doesn’t install it whilst downloading, the installation file he gets is locked and can only be installed on that same computer. If he tries to use the installer on another computer it must refuse or ask for an activation key, which he must now buy from us.
Alternatively just have users download the executable file from Microsoft store, and when they install it should be a 10 days trial version after which it must call for the activation key. I am not sure how to implement these scenarios. Please help.
