Status: RESOLVED WONTFIX

(Firefox :: Installer, defect)

Description

Attachment: Screenshot of installer UAC dialog

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:32.0) Gecko/20100101 Firefox/32.0
Build ID: 20140825202822

Steps to reproduce:

I am running the Firefox (32.0) installer to install the browser into a non-priviledged location (i.e. outside of Program Files). I am using the /INI command line option to run a silent install. This is happening from a CI process so it is mandatory to run without user interaction. The command line of the installer is:
C:\usr\WebChannel\workspaces\Playground\browserinstall-test\browser-installer\firefox2522360157411262402.exe /INI=C:\usr\WebChannel\workspaces\Playground\browserinstall-test\browser-installer\firefox5864794478100568118.ini


Actual results:

When the installer is started, it requests elevated priviledges, triggering a UAC popup. A screenshot of the popup is attached.


Expected results:

The installer should not request a UAC popup unless installing into a priviledged location. Alternatively, the installer should provide a command line switch/INI option to suppress UAC requests and always run non-elevated.

Attachment: Installer INI file

Attaching the INI file used during the installation. This is a template where the target installation directory is replaced before the installer is called, so at the time the installer runs it will have a valid directory path.

We show a UAC prompt, but we allow rejecting it to continue installing to a non-privileged location. We don't show the prompt any later than we do because we use that signal to select the default directory.
