Thank you for your reply. QB 2020 is already installed on my laptop and has been for over a year with no issues. The last available update in May successfully updated my QB without a hiccup. I am stuck in the "You must install this update to continue using QB", clicking "Install Now", accepting "Do you want this app to make changes to this computer?" and nothing downloads. I can't access anything without this update apparently. The laptop runs on Windows 10 and has all the latest updates related to it. I have avoided upgrading to Windows 11.
