Firefox version 53.x 64 bit will not run on my computer (Win7 x64)

I have v50 and it works. When Firefox auto updated yesterday it no longer ran. When I reinstalled v50 it ran again. In the interim I had scanned my computer for malware; no malware. I am convinced therefore that the problem lies with the upgrade rather than my system. Wouldn't you agree?

When it crashes error 0xc0000022 is shown.

can you install firefox 53 while you run windows 7 in safe mode? https://support.microsoft.com/help/17419/windows-7-advanced-startup-options-safe-mode

Sure I can install it in safe mode but it doesn't run no matter how I install it. My hypothesis is that the 64 bit version of Firefox is incompatible with Windows 7 and was probably only tested on Windows 10. i can install and run the 32 bit version of v.53.x on Windows 7 or I can try to use v50.x 64 bit without upgrades.

I had the same problem Akido a while back with the 64 bit version on Win 7 Pro 64 Bit and had to download the 32bit version of Firefox which is working fine now.

So, to follow up; Is there a plan to make the 64 bit version of Firefox compatible with Windows 7 in a susbequent update??
