Horizon Agent Direct-Connection Plug-In (formerly View Agent Direct-Connection Plug-In) is packaged in an installer file that you can download from the VMware website and install. You can install Horizon Agent Direct-Connection Plug-In on a Windows or Linux machine where Horizon Agent is already installed.

Prerequisites

  • Verify that Horizon Agent is installed on the machine.
    • For information on installing Horizon Agent on a Windows machine, see Windows Desktops and Applications in Horizon. If your environment does not include Connection Server, install Horizon Agent from the command line and specify a parameter that tells Horizon Agent not to register with Connection Server. See Windows - Set Up the Desktop for HTML Access.
    • For information on installing Horizon Agent on a Linux machine, see "Install Horizon Agent on a Linux Virtual Machine" and "Command-Line Options for Installing Horizon Agent for Linux" in Linux Desktops and Applications in Horizon. To support direct connections to single-session desktops, install Horizon Agent with default installation parameters. To support direct connections to multi-session desktops and applications, install Horizon Agent with the --multiple-session parameter included.
  • Enable the screen DMA setting for virtual machines on vSphere 6.0 and later. If screen DMA is not enabled, users see a black screen when they connect to the remote desktop. For more information on how to set the screen DMA, see the VMware Knowledge Base (KB) article 2144475 http://kb.vmware.com/kb/2144475.
