We need a bit more information to figure out what's going on here.

First, could you navigate to the "Update" section of about:preferences and find a checkbox labelled "Use background service to install updates". Let me know whether that checkbox is checked.

Second, I would also like to see the update console logs. To obtain these, navigate to about:config and search for "app.update.log". Set that preference to true. Then open the browser console: Hamburger menu -> Web Developer -> Browser Console. Now check for an update by navigating to the "Update" section of about:preferences and clicking "Check for Update". The Browser Console should now contain some lines beginning with "AUS:SVC" (you can filter by that using the box at the top, if you want). Please post those messages to this bug so that I can take a look.

Attachment: AUS:SVC log messages during a failed update

In about:preferences, automatic updates and the background service are enabled.

See the attached file for the AUS:SVC log.

This is excellent, thank you. This log indicates that the update is successfully getting downloaded, and the updater is attempting to use the Mozilla Maintenance Service, but that the update process itself is failing. Could you please attach the update logs so that I can take a look at them? Based on the console log you provided, the update logs should be located in:

C:\ProgramData\Mozilla\updates\308046B0AF4A39CB\updates

Could you please locate that directory and attach any log files there? They will probably be called "last-update.log" and "backup-update.log".

Closing this bug since we have been waiting for needed information from the reporter for over a month.
