Desktop viewer toolbar doesn’t show up in session

The black Desktop Viewer toolbar does not show up in the user XenApp or XenDesktop ICA session.


The issue is caused by NOT having the ShowDesktopViewer parameter set to On in the WebInterface.conf file on the Web Interface server.


To resolve this issue, complete the following procedure:

  • Logon to the machine hosting the Web Interface as an administrator user.
  • Open the C:InetpubwwwrootCitrixXenAppconf folder for Web Interface connections.
  • Open the C:InetpubwwwrootCitrixPNAgentconf folder for PNAgent connections.
  • Edit the WebInterface.conf file in both these locations.
  • Update the configuration file to remove the ‘#’ and set ShowDesktopViewer=On.
