Description

User unable to launch the published application
"The published application you requested failed to start. The Citrix Server is unable to process your request to start this published application. Please try again. If the problem persists, contact your administrator."

Environment

Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

Resolution

On the VDA server navigate to the below registry Location 
HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Ica\Session
Right click on Session and select Permission
Check if TermService is added and has Full control and Read permission
If Term service is not present add NT Authority\ Network Service and provide full permission. 

Problem Cause

Term Service is added to the Session registry's permissions by default while installing the VDA
Some Group policy or Installer restriction can prevent adding the proper and required permissions
