I appreciate you for bringing this matter in the Community forum, Bungaloo. Since the QuickBooks Desktop 2021 is the last supported version and you're still in QBDT 2015, this could be the reason why you can't proceed with the registration process. To resolve this, ensure that you're using the latest version of QuickBooks and that all functionalities, including registration, work smoothly. Let me also add other solutions that can help:
We can restart (close and reopen) the QuickBooks to refresh the program as this resolves temporary glitches and can help you proceed with the registration process. We also need to ensure you have a stable internet connection, as a weak connection can cause the registration screen to stall. Consider restarting your router or modem if necessary.
Additionally, if you are considering updating your QuickBooks, you can refer to this article with adding and setting soles for users: QuickBooks Desktop users and restrictions.
