Using PN Agent with Citrix Web Interface 5.2 and PS 4
I ran into an issue while upgrading components in preparation for our XenApp 5 migration where after installing Web Interface 5.2 I could connect and see my published applications but when I tried to launch one I would get an error “Citrix online plug-in could not contact the server”.
The solution is to edit the WebInterface.conf in your PN Agent IIS site and add a line “RequireLaunchReference=off”.
