Firewall, firewall, firewall. Win7's firewall is likely blocking ports. When View says "Waiting for Agent" that means it's waiting for the agent to respond. This can happen waiting for a service to start or if a firewall blocks it.
And the "Empty pool" error is because you've logged into the only desktop (likely via vCenter -- REMEMBER: This counts as a connection as far as RDP/PCoIP are concerned and since those are SINGLE USER protocols you won't be able to log into View if you've logged in via the vCenter console). Log off vCenter and try connecting with the View Client would be a better test.
