PS4.0 Farm hosted on Citrix Web Interface 5.4

Well just started working in a new company and for some reason, they still have PS4.0 running in Prod…

By default, Citrix Web Interface 5.4 will not allow for PS4 connectivity. However there are some tricks you can do to get this working

  • Go to the site’s root normally located under C:\inetpub\wwwroot\Citrix\NameOfSite\conf\
  • Open WebInterface.conf
  • Look for the RequireLaunchReference syntax
  • Set the setting to “Off” (RequireLaunchReference=Off)

Once that is done, you will be able to open PS4.0 apps directly from your WI 5.4 implementation for both CSG (CAGs/NetScalers) or direct WI connections.

If you are utilizing the new Receiver Client, you may run into an issue where apps do not open. I did run into it on one of my Windows Laptops (Mac worked as usual :P)

  • Uninstall all Citrix Online Plugins or Receiver
  • Delete folder c:\program files\citrix
  • Delete following registry key : HKLM/HKCU/Software/Citrix
  • Install Citrix client
