If client systems connect from outside the corporate firewall, use a Unified Access Gateway appliance so that client systems do not require a VPN connection. If your company has an internal wireless network to provide routable access to remote desktops that devices can use, you do not need to set up Unified Access Gateway or a VPN connection.

Display protocols
  • PCoIP
  • VMware Blast
  • RDP
Network protocols
  • IPv4
  • IPv6

During a custom Horizon Client installation, you can enable the automatic selection of the Internet protocol. For more information, see Enabling Automatic Internet Protocol Selection. For information about using Horizon in an IPv6 environment, see the Horizon Installation document.

Hardware requirements for PCoIP and VMware Blast
  • x86-based processor with SSE2 extensions, with an 800 MHz or faster processor speed.
  • Available RAM above system requirements to support various monitor setups. Use the following formula as a general guide. The unit of measurement is pixels.
    20 MB + (24 * (# monitors) * (monitor width) * (monitor height))
    In general, you can use the following calculations.
    1 monitor: 1600 x 1200: 64 MB
    2 monitors: 1600 x 1200: 128 MB
    3 monitors: 1600 x 1200: 256 MB
Hardware requirements for RDP
  • x86-based processor with SSE2 extensions, with an 800 MHz or faster processor speed.
  • 128 MB RAM.
Software requirements for RDP
  • For Windows 10, use RDP 10.0.
  • The agent installer configures the local firewall rule for inbound RDP connections to match the current RDP port of the host operating system, which is typically 3389. If you change the RDP port number, you must change the associated firewall rules.

You can download Remote Desktop Client versions from the Microsoft Download Center.

Video and graphics requirements
  • Graphics card that supports Direct3D 11 Video.
  • Latest video and graphics card drivers.
.NET Framework requirements
The Horizon Client installer requires .NET Framework version 4.5 or later. The installer checks whether .NET Framework version 4.5 or later is installed before installation. If the client machine does not meet this prerequisite, the installer downloads the latest version of .NET Framework automatically.
To use Horizon Client, .NET Desktop Runtime for Windows x86 version 5.0 or later is required. The Horizon Client installer installs a recent version of Desktop Runtime. After you install Horizon Client, you can update Desktop Runtime from
