Short of the long I was unable to update several agents to 5.3 becuase the 5.2 msi couldn't be found.
I followed the directions on this page (VMware KB: UpgradingVMware View Agent and View Composer fails with the error: The feature you are trying to use is o…) and from there installed the 5.3 agent.
This worked on 3 test systems. When I went live 2 agents broke. I can RDP but can't use the Client to connect and get a response that tells me the resource isn't available.
I looked in Horizon View Admin and they are listed as agent unreachable, pairing state, in pairing.
I've done the following.
Uninstalled the 5.3 agent.
Uninstalled the tools.
Reinstalled both.
Removed them from the pool inventory and added them back.
These are Win7 systems.
Any help would be very appreciated.
