I have successfully upgraded to SourceTree 2.3.1.0 on my local development laptop that is running windows 10 however when I tried to do the same update on my production server that is running Windows Server 2012 R2 I'm having an issue that I can't get around.
On my prod server I get to the second step which is "License Agreement" and when I click on "Use an existing account" I get a popup that is blank. The first time that I ran this I got an error message that said something about adding "id.atlassian.com" to my Trusted Sites in IE. I did that and then come back to re-run the install and it gives me the blank screen.
I've also changed my default web browser to be Firefox in the hopes that it would do something different with the popup but nothing.
Please help.
