Firefox will not install on any of my Windows 10 computers. It just continuously has a moving bar, saying 'Now installing.'

Over the last month or so, I've had trouble installing Firefox version 55 (latest version) on any new Windows 10 laptops. It just continuously has a moving bar, saying 'Now installing.' This is on Windows 10 ver 10.0.15063, which is the latest version of Windows 10, to my knowledge. This happens on all my new computers, right out of the box after installing a fresh copy of Windows 10. Does anyone have any ideas on how to get it to install? I've tried disabling Windows Defender, which didn't help.
