VADC does support the Blast protocol but there are additional setup steps to host the static web server content for the actual HTML Access Client.
Normally, in a full View environment the HTML5 client is hosted on the Connection Server, but in a typical VADC deployment there is no Connection Server.
I'll publish some manual setup steps for this soon. When this is published and set up, you'll be able to just point a browser at the virtual desktop to get Blast access.
In the mean time you can use all other clients to access the View desktop directly with PCoIP or RDP.
