I access Horizon via work portal.   However, when launching the portal link for my VMware Horizon Desktop, I get an error "Google Chrome OS can't open this page".

I have installed the VMware Horizon Client 5.4.1, and it will launch from the Shelf.

But I'm not able to authenticate using that method.  I must authenticate via the portal.

I was recently moved to VMware Horizon, and it worked fine when I was on Citrix.
