Why does my zero client not badge out when using Imprivata and VMware Horizon 2111

Scenario:
After upgrade of VMware Horizon Agent from 2106 to 2111 when tapping out the session the session is no longer disconnected however the desktop is locked.

Impact:
Customers using PCoIP zero clients and Imprivata OneSign connecting to VMware VDI.

Fix:
 The newer Horizon Agent 8.4 utilizes a 64 bit version of PCoIP that may not be loading correctly. Please add this key and test:
 NOTE: When ever modifying the registry if you are unsure take a back up of the registry first.

1. Create the following key
HKEY_LOCAL_MACHINE\SOFTWARE\Teradici\VChan\Plugins\OneSignVC
 
2. Under key OneSignVC create the following String Value entry.
Name = dll
Type = REG_SZ
Data = C:\Program Files (x86)\Imprivata\OneSign Agent\x64\ssovcd.dll
