Firefox 47.0.1

Firefox 47.0.1 Download Filehippo

I've downloaded this a couple of days ago (on my Windows 10 laptop); trying to find out what it does, I get a notification from UAC : 'this app can't run on this PC' .
Trying to find out why , I only get: 'Incompatibel Program'
Maybe it wasn't such a bright idea to download something, not knowing what it actually does , but hey: I totally trust Firefox ........
It's still in one of my folders, but I can't open it .
Before having a go at Microsoft, I should at least be able to tell them what this app is/does; can anybody tell me ?
