When you install Horizon Agent on a virtual machine, you can select or deselect 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 learn which features are supported on which guest operating systems, see "Feature Support Matrix for Horizon Agent" in the View Architecture Planning document.

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.

All custom setup options are selected by default except USB Redirection, Scanner Redirection, Smartcard Redirection, Serial Port Redirection, Flash Redirection, Skype for Business, and VMware Horizon Instant Clone Agent.

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

Option

Description

Core

Installs the core functionality.

USB Redirection

Gives users access to locally connected USB devices on their desktops.

USB redirection is supported on remote desktops that are deployed on single-user machines. In addition, redirection of USB flash drives and hard disks is supported on RDS desktops and applications.

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

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.

Real-Time Audio-Video

Redirects webcam and audio devices that are connected to the client system so that they can be used on the remote desktop.

Client Drive Redirection

Allows Horizon Client users to share local drives with their remote desktops.

After this option is installed, no further configuration is required on the remote desktop.

Client Drive Redirection is also supported on RDS desktops and applications and on VDI desktops that run on 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.

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. It is not supported if you install it with VMware Tools.

vRealize Operations Desktop Agent

Provides information that allows vRealize Operations for View to monitor View desktops.

VMware Horizon 7 Persona Management

Synchronizes the user profile on the local desktop with a remote profile repository, so that users have access to their profiles whenever they log in to a desktop.

Scanner Redirection

Redirects scanning and imaging devices that are connected to the client system so that they can be used on the remote desktop or application.

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

Scanner redirection is available in Horizon 6.0.2 and later releases.

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.

Smartcard Redirection

Lets users authenticate with smart cards when they use the PCoIP or Blast Extreme display protocol. This option is not selected by default.

Smartcard Redirection is supported on remote desktops that are deployed on single-user machines.

VMware Horizon Instant Clone Agent

Lets this virtual machine be the parent VM of an instant-clone desktop pool. This option is not selected by default. If you select this option, you cannot select the VMware Horizon View Composer Agent option.

Local Printer Redirection

Local printer redirection is designed for the following use cases:

  • Printers directly connected to USB or serial ports on the client device

  • Specialized printers such as bar code printers and label printers connected to the client

  • Network printers on a remote network that are not addressable from the virtual session.

VMware Virtualization Pack for Skype for Business

Makes optimized audio and video calls with Skype for Business inside a virtual desktop. This option is not selected by default. You must select the option to install it.

Table 2. Horizon Agent Features That Are Installed Automatically (Not Optional)

Feature

Description

PCoIP Agent

Users can browse, search, and open Windows applications and files, choose favorite applications and files, and switch between running applications, all without using the Start menu or Taskbar.
