Installer hangs on browser authentication
I've tried several apps and the main Creative Cloud installer (I have the all apps plan) and it hangs every time I get to the part requiring browser identification, here:

I get taken to the browser window (in Chrome, regardless of my default browser settings) and it says:

But the installer does not proceed, and I end up here:

If I click on "If your browser is not responding, sign in here" nothing happens. I've uninstalled, tried again, then used the Adobe CC cleaner tool and removed everything, tried again, I've gone into the registry and deleted all Adobe keys, I've run as admin and as not, I've restarted and tried installing in Safe Mode with networking. Same results. I've also tried signing out before being taken to the browser, then signing in, then getting the "You're all set!" screen again. I've tried doing that with a different account. Nothing has worked.
Prior to this I had only Photoshop installed, and it worked fine. The issue started when I switched to the 'all apps' plan and tried to install acrobat. The installer hung 1/2 way through the Acrobat install. I quit, tried again, and got the above. Then tried all the steps I mention above. I also tried installing other apps, which is why the screengrab above shows my attempt to install XD.
I've explored all the forums and FAQs and tried everything suggested in them.
