Installer telemetry misses some cases where installation would be aborted, specifically:
The OS is too old (Windows <10)
The hardware is missing support for a required feature (SSE2)
There is insufficient space on the drive
The target location is not writable
Also, the default error reported by telemetry indicates that the user cancelled the download, regardless of the actual error.
This change addresses these issues.
This change also modifies the URL that the user is directed to, when
we determine that they are running on Windows 7 or 8. The old URL was
the System Requirements page. The new URL is:
https://support.mozilla.org/kb/firefox-users-windows-7-8-and-81-moving-extended-support
