When I first launch it comes up with a credentials window. Two versions of the client (4.5 and 5.5) tested the same.
I had some issues with certificates after the upgrade but was able to resolve those. Turned off the Composer because we aren't using it and it is being deprecated in newer versions anyway. I recently upgraded the Connection and Security servers to 7.13.
We've had Horizon View installed and working on version 7.4.
