Description

The pooled random VDA will go into Unregistered with a status of "Initialization status"

Resolution

The solution was to include MSRA.exe in UviProcessExcludes registry and remove the install.vbs script from the APP-V 

Problem Cause

CtxUvi is the VDA's hooking engine. For security, it has the ability to disable hooking when it detects tampering or it's unable to perform integrity checks. When hooking is disabled, for all intents and purposes, the VDA is no longer functional. However, the VDA remains registered and sessions can still be brokered to the VDA, which will result in a nonfunctional session for the user (grey screen)
