When you install View Agent on an RDS host, you can select custom setup options. In addition, View Agent installs certain features automatically on all guest operating systems on which they are supported. These features are not optional.

To change custom setup options after you install the latest View Agent version, you must uninstall and reinstall View Agent. For patches and upgrades, you can run the new View Agent installer and select a new set of options without uninstalling the previous version.

Table 1. View Agent Custom Setup Options for an RDS Host in an IPv4 Environment
Option Description
USB Redirection Gives users access to locally connected USB storage devices.

Specifically, redirection of USB flash drives and hard disks is supported in RDS desktops and applications. Redirection of other types of USB devices, and other types of USB storage devices such as security storage drives and USB CD-ROM, is not supported in RDS desktops and applications.

This setup option is not selected by default. You must select the option to install it. This option is available on RDS hosts that run Windows Server 2012 or 2012 R2 but not Windows Server 2008 R2.

For guidance on using USB redirection securely, see the View Security guide. For example, you can use group policy settings to disable USB redirection for specific users.

HTML Access Allows users to connect to RDS desktops and applications by using HTML Access. The HTML Access Agent is installed when this setup option is selected. This agent must be installed on RDS hosts to allow users to make connections with HTML Access
3D RDSH Provides 3D graphics support to applications that run on this RDS host.
View Composer Agent Select this option if this machine is a parent virtual machine for the creation of an automated farm. Do not select this option if this machine is an RDS host in a manual farm.
Client Drive Redirection Allows Horizon Client users to share local drives with their RDS desktops and applications.

After this setup option is installed, no further configuration is required on the RDS host.

Client Drive Redirection is also supported on VDI desktops that run on single-user virtual machines and unmanaged machines.

Virtual Printing Lets users print to any printer available on their client computers. Users do not have to install additional drivers on their desktops.

In Horizon 6.0.1 and later, virtual printing is supported on the following remote desktops and applications:

  • Desktops that are deployed on single-user machines, including Windows Desktop and Windows Server machines
  • Desktops that are deployed on RDS hosts, where the RDS hosts are virtual machines
  • Hosted Apps
  • Hosted Apps that are launched from Horizon Client inside remote desktops

In Horizon 6.0 and earlier, virtual printing is supported on desktops that are deployed on single-user, Windows Desktop machines.

The virtual printing feature is supported only when you install it from View Agent. It is not supported if you install it with VMware Tools.

vRealize Operations Desktop Agent Lets vRealize Operations Manager work with vRealize Operations Manager for Horizon.
Scanner Redirection Redirects scanning devices that are connected to the client system so that they can be used on the RDS desktop or application.

You must install the Desktop Experience feature in the Windows Server operating system on the RDS hosts to make this option available in the View Agent installer.

This setup option is not installed by default on Windows Server guest operating systems. You must select the option to install it.

Scanner redirection is available in Horizon 6.0.2 and later releases.

In an IPv6 environment, there are no optional features.

Table 2. View Agent Features That Are Installed Automatically on an RDS Host
Option Description
PCoIP Agent

Allows users to connect to applications and RDS desktops using the PCoIP display protocol.

You must install this component if you plan to create application pools because users can only connect to applications using PCoIP.

Windows Media Multimedia Redirection (MMR) Provides multimedia redirection for RDS desktops. This feature delivers a multimedia stream directly to the client computer, allowing the multimedia stream to be processed on the client hardware instead of the remote ESXi host.
Unity Touch Allows tablet and smart phone users to interact with Windows applications that run on the remote desktop. Users can browse, search, and open Windows applications and files, choose favorite applications and files, and switch between running applications without using the Start menu or Taskbar.
PSG Agent Installs the PCoIP Secure Gateway on RDS hosts to implement the PCoIP display protocol for desktop and application sessions that run on RDS hosts.
VMwareRDS Provides the VMware implementation of Remote Desktop Services functionality.

In an IPv6 environment, the automatically installed features are PCoIP Agent, PSG Agent, and VMwareRDS.

For additional features that are supported on RDS hosts, see "Feature Support Matrix for View Agent" in the View Architecture Planning document.
