We’ve recently been receiving reports of a license error (0x87E107D0) that occurs when installing the current app from the Microsoft Store. Our Windows team is working with Microsoft directly, but we have not yet found a fix.
In the meantime, you can download and install a previous version of the Olive Tree Bible App from the following page: https://www.olivetree.com/pc/
When you have the app downloaded, you will need to log in, sync, and download your books. You can find articles on how to use this app here.
