1580148 - Updates cannot be installed for non-privileged user, even when installed for the user

Status: RESOLVED WORKSFORME

(Toolkit :: Application Update, defect, P3)

Description

[Julius B.]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:70.0) Gecko/20100101 Firefox/70.0

Steps to reproduce:

• Installed Firefox 70.0b4 per-user into %localappdata% be denying the UAC prompt
• Checked for updates via Hamburger menu > Help > About Firefox
• Pressed the "restart to update" button

Windows 10
Firefox 70.0b4

Actual results:

Sometimes, Firefox starts without installing the update
Sometime, Firefox shows an error message that a previous update still needs to be run, and the system needs to be restarted. A restart doesn't help, and Firefox cannot be restarted after that. What's even worse, it cannot be uninstalled, because the same message appears when starting the uninstaller. When this happens, the only way to fix Firefox is to re-download the installer, and reinstall it.

Expected results:

In all cases (installed for non-privileged user and update triggered from the same user; installed system-wide and update triggered from a non-privileged user), the update should just be installed.
