Cannot install Firefox 64-bit on Windows 10 x64 (Insider Build 15019)

[Immanuel]

For both version Firefox 51 x64 and Firefox Nightly x64, the installer does not detect Insider build as being Windows 10.

See attached screenshots.



I have submitted 2 bugs on bugzilla:

Bug 1336268 - Cannot install Firefox 64-bit 51.0.1 on Windows 10 x64 (insider build 15019)
https://bugzilla.mozilla.org/show_bug.cgi?id=1336268

and
Bug 1336269 - Cannot install Nightly 64-bit 54 on Windows 10 x64 (insider build 15019)
https://bugzilla.mozilla.org/show_bug.cgi?id=1336269



Any help to confirm these bugs would be greatly appreciated.


To reproduce, try installing from scratch the 64-bit version of either the stable or Nightly version of Firefox in Windows 10 Insider build (I am on 15019) and report back.

I just installed Firefox 51.0.1 x64 on my Insider 15019 without any problems so I cannot reproduce the problem...

Where did you get the installation file for firefox??
I always get mine from here: http://archive.mozilla.org/pub/firefox/releases/

Unfortunately, I've already moved on to 15025, but.....
Just for the heck of it, I installed the 32 bit version of Firefox
Uninstalled it and then installed the 64 bit version.
Both of which installed and ran fine on the latest Insider Preview Build.
