Unable to authorize Bitbucket account when installing Sourcetree

[cpolstra1]

I downloaded SourceTreeSetup-3.3.8.exe on my Windows 10 machine.  I click on it. It says I need to register it to my Atlassian Bitbucket Account. I click Bitbucket -> opens in browser. Says "Authenticated" and then the installer hangs for about 2 minutes and then reverts back to the Registration page. Anyone have any idea of how to get this working? 

EDIT: Tried disabling all of my extensions. Tried in Chrome and Firefox both. Also opened both the browser and installer as admin. Also created a new user and the same hangup happens.
