When you install Horizon Agent on an RDS host, you can select custom setup options. In addition, Horizon 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 Horizon Agent version, you must uninstall and reinstall Horizon Agent. For patches and upgrades, you can run the new Horizon Agent installer and select a new set of options without uninstalling the previous version.

Table 1. Horizon Agent Custom Setup Options for an RDS Host in an IPv4 Environment



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 information about using USB redirection securely, see the View Security document. For example, you can use group policy settings to disable USB redirection for specific users.

HTML Access

Enables 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 enable users to make connections with HTML Access


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

Enables 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 remote desktops that run on single-user virtual machines and on unmanaged machines.

Virtual Printing

Enables users to print to any printer available on their client computers. Users do not need to install additional drivers on their desktops.

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.

  • Remote applications.

  • Remote applications that are launched from Horizon Client inside remote desktops (nested sessions).

The virtual printing feature is supported only when you install it from Horizon Agent. If you install it with VMware Tools, it is not supported.

vRealize Operations Desktop Agent

Enables vRealize Operations Manager to 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 Horizon Agent installer.

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

HTML5 Multimedia Redirection

Redirects HTML5 multimedia content in a Chrome browser to the client for performance optimization.

This setup option is not installed by default. You must select the option to install it.

VMware Client IP Transparency

Enables remote connections to Internet Explorer to use the client's IP address instead of the remote desktop machine's IP address.

This setup option is not selected by default. You must select the option to install it.

Instant Clone

Enables the creation of instant-clone virtual machines on a farm of RDS hosts.

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

In an IPv6 environment, the setup options are similar to IPv6.

Table 2. Horizon Agent Features That Are Installed Automatically on an RDS Host



PCoIP Agent

Enables users to use the PCoIP display protocol to connect to applications and RDS desktops.

Windows Media Multimedia Redirection (MMR)

Provides multimedia redirection for RDS desktops. This feature delivers a multimedia stream directly to the client computer, which enables the multimedia stream to be processed on the client hardware instead of on the remote ESXi host.

Unity Touch

Enables 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.


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 Horizon Agent" in the View Architecture Planning document.
