Website Visitors:

The system requirements in this topic are valid when this product version released. System requirements components not covered in this topic (such as StoreFront, host systems, receivers and plug-ins, and Provisioning Services) are described in their respective documentation.

Important: Review the Prepare to install topic before beginning an installation.

Unless otherwise noted, the component installer deploys software prerequisites automatically (such as .NET and C++ packages) if they are not detected on the machine. The Citrix installation media also contains some of this prerequisite software.

The installation media contains several third-party components. Before using the Citrix software, check for security updates from the third party, and install them.

The disk space values are estimates only, and are in addition to space needed for the product image, operating system, and other software.

If you install all the core components (Controller with SQL Server Express, Studio, Director, StoreFront, and Licensing) on a single server, you need a minimum of 3 GB of RAM to evaluate the product; more is recommended when running an environment for users. Performance will vary depending on your exact configuration, including the number of users, applications, desktops, and other factors.

Quick links to topic sections:

Important: After you install a component on a Windows Server 2012 R2 system, use the Kerberos Enable Tool (XASsonKerb.exe) to ensure the correct operation of Citrix Kerberos authentication. The tool is located Support > Tools > XASsonKerb folder on the installation media; you must have local administrator privileges to use the tool. To ensure correct Kerberos operation, run xassonkerb.exe –install from a command prompt on the server. If you later apply an update that changes the registry location HKLM\System\CurrentControlSet\Control\LSA\OSConfig, run the command again. To see all available tool options, run the command with the –help parameter.

Delivery Controller

Supported operating systems:

  • Windows Server 2012 R2, Standard and Datacenter Editions
  • Windows Server 2012, Standard and Datacenter Editions
  • Windows Server 2008 R2 SP1, Standard, Enterprise, and Datacenter Editions

Requirements:

  • Disk space: 100 MB. Connection leasing (which is enabled by default) adds to this requirement; sizing depends on the number of users, applications, and mode (RDS or VDI). For example, 100,000 RDS users with 100 recently-used applications require approximately 3 GB of space for connection leases; deployments with more applications may require more space. For dedicated VDI desktops, 40,000 desktops require at least 400-500 MB. In any instance, providing several GBs of additional space is suggested.
  • Microsoft .NET Framework 3.5.1 (Windows Server 2008 R2 only).
  • Microsoft .NET Framework 4.5.1 (4.5.2 is also supported).

Virtual Delivery Agent (VDA) for Windows Desktop OS

Supported operating systems:

  • Windows 8.1, Professional and Enterprise Editions
  • Windows 8, Professional and Enterprise Editions
  • Windows 7 SP1, Professional, Enterprise, and Ultimate Editions

To use the Server VDI feature, you can use the command line interface to install a VDA for Windows Desktop OS on a supported server operating system; seeServer VDI for guidance.

  • Windows Server 2012 R2, Standard and Datacenter Editions
  • Windows Server 2012, Standard and Datacenter Editions
  • Windows Server 2008 R2 SP1, Standard, Enterprise, and Datacenter Editions

Requirements:

  • Microsoft .NET Framework 3.5.1 (Windows 7 only)
  • Microsoft Visual C++ 2005, 2008, and 2010 Runtimes (32-bit and 64-bit)

Remote PC Access uses this VDA, which you install on physical office PCs.

Several multimedia acceleration features (such as HDX MediaStream Windows Media Redirection) require that Microsoft Media Foundation be installed on the machine on which you install the VDA. If the machine does not have Media Foundation installed, the multimedia acceleration features will not be installed and will not work. Do not remove Media Foundation from the machine after installing the Citrix software; otherwise, users will not be able to log on to the machine. On most Windows 8.1, Windows 8, and Windows 7 editions, Media Foundation support is already installed and cannot be removed. However, N editions do not include certain media-related technologies; you can obtain that software from Microsoft or a third party.

During VDA installation, you can choose to install the HDX 3D Pro version of the VDA for Windows Desktop OS. That version is particularly suited for use with DirectX and OpenGL-driven applications and with rich media such as video.

You cannot install a current version of the VDA on a machine running Windows XP or Windows Vista; however, you can install an earlier Virtual Desktop Agent version on those operating systems, if needed. See CTX140941 for details. The Remote PC Access version in this release is not supported on Windows Vista operating systems.

Virtual Delivery Agent (VDA) for Windows Server OS

Supported operating systems:

  • Windows Server 2012 R2, Standard and Datacenter Editions
  • Windows Server 2012, Standard and Datacenter Editions
  • Windows Server 2008 R2 SP1, Standard, Enterprise, and Datacenter Editions

The installer automatically deploys the following requirements, which are also available on the Citrix installation media in the Support folders:

  • Microsoft .NET Framework 4.5.1 (4.5.2 is also supported)
  • Microsoft .NET Framework 3.5.1 (Windows Server 2008 R2 only)
  • Microsoft Visual C++ 2005, 2008, and 2010 Runtimes (32-bit and 64-bit)

The installer automatically installs and enables Remote Desktop Services role services, if they are not already installed and enabled.

Several multimedia acceleration features (such as HDX MediaStream Windows Media Redirection) require that the Microsoft Media Foundation be installed on the machine on which you install the VDA. If the machine does not have Media Foundation installed, the multimedia acceleration features will not be installed and will not work. Do not remove Media Foundation from the machine after installing the Citrix software; otherwise, users will not be able to log on to the machine. On most Windows Server 2012 R2, Windows Server 2012, and Windows Server 2008 R2 editions, the Media Foundation feature is installed through the Server Manager (for Windows Server 2012 R2 and Windows Server 2012: ServerMediaFoundation; for Windows Server 2008 R2: DesktopExperience). However, N editions do not include certain media-related technologies; you can obtain that software from Microsoft or a third party.

HDX - Desktop Composition Redirection

The Windows user device or thin client must support or contain:

  • DirectX 9

  • Pixel Shader 2.0 (supported in hardware)

  • 32 bits per pixel

  • 1.5 GHz 32-bit or 64-bit processor

  • 1 GB RAM

  • 128 MB video memory on the graphic card or an integrated graphics processor

    HDX queries the Windows device to verify that it has the required GPU capabilities and automatically reverts to server-side desktop composition if it does not. List the devices with the required GPU capabilities that do not meet the processor speed or RAM specifications in the GPO group for devices excluded from Desktop Composition Redirection.

The minimum available bandwidth is 1.5 Mbps; recommended bandwidth is 5 Mbps. Those values incorporate end-to-end latency.

HDX - Windows Media delivery

The following clients are supported for Windows Media client-side content fetching, Windows Media redirection, and real-time Windows Media multimedia transcoding: Receiver for Windows, Receiver for iOS, and Receiver for Linux.

To use Windows Media client-side content fetching on Windows 8 devices, set the Citrix Multimedia Redirector as a default program: in Control Panel > Programs > Default Programs > Set your default programs, select Citrix Multimedia Redirector and click either Set this program as default orChoose defaults for this program.

GPU transcoding requires an NVIDIA CUDA-enabled GPU with Compute Capability 1.1 or higher; see http://developer.nvidia.com/cuda/cuda-gpus.

HDX - Flash Redirection

The following clients and Adobe Flash Players are supported:

  • Receiver for Windows (for second generation Flash Redirection features) - Second generation Flash Redirection features require Adobe Flash Player for Other Browsers, sometimes referred to as an NPAPI (Netscape Plugin Application Programming Interface) Flash Player
  • Receiver for Linux (for second generation Flash Redirection features) - Second generation Flash Redirection features require Adobe Flash Player for other Linux or Adobe Flash Player for Ubuntu.
  • Citrix Online plug-in 12.1 (for legacy Flash Redirection features) - Legacy Flash Redirection features require Adobe Flash Player for Windows Internet Explorer (sometimes referred to as an ActiveX player).

The major version number of the Flash Player on the user device must be greater than or equal to the major version number of the Flash Player on the server. If an earlier version of the Flash Player is installed on the user device, or if the Flash Player cannot be installed on the user device, Flash content is rendered on the server.

The machines running VDAs require:

  • Adobe Flash Player for Windows Internet Explorer (the ActiveX player)
  • Internet Explorer versions 7, 8, 9, 10, 11 (in non-Modern UI mode). Flash redirection requires Internet Explorer on the server; with other browsers, Flash content is rendered on the server.
  • Protected mode disabled in Internet Explorer (Tools > Internet Options > Security tab > Enable Protected Mode check box cleared). Restart Internet Explorer to effect the change.

HDX 3D Pro

When installing a VDA for Windows Desktop OS, you can choose to install the HDX 3D Pro version.

The physical or virtual machine hosting the application can use GPU Passthrough or Virtual GPU (vGPU):

  • GPU Passthrough is available with Citrix XenServer. GPU Passthrough is also available with VMware vSphere and VMware ESX, where it is referred to as virtual Direct Graphics Acceleration (vDGA).
  • vGPU is available with Citrix XenServer; see www.citrix.com/go/vGPU (Citrix My Account credentials required).

Citrix recommends that the host computer have at least 4 GB of RAM and four virtual CPUs with a clock speed of 2.3 GHz or higher.

Graphical Processing Unit (GPU):

  • For CPU-based compression (including lossless compression), HDX 3D Pro supports any display adapter on the host computer that is compatible with the application being delivered.
  • For optimized GPU frame buffer access using the NVIDIA GRID API, HDX 3D Pro requires NVIDIA Quadro cards with the latest NVIDIA drivers. The NVIDIA GRID delivers a high frame rate, resulting in a highly interactive user experience.
  • For vGPU using XenServer, HDX 3D Pro requirements include NVIDIA GRID K1 and K2 cards.

User device:

  • HDX 3D Pro supports all monitor resolutions that are supported by the GPU on the host computer. However, for optimum performance with the minimum recommended user device and GPU specifications, Citrix recommends a maximum monitor resolution for user devices of 1920 x 1200 pixels for LAN connections, and 1280 x 1024 pixels for WAN connections.
  • Citrix recommends that user devices have at least 1 GB of RAM and a CPU with a clock speed of 1.6 GHz or higher. Use of the default deep compression codec, which is required on low-bandwidth connections, requires a more powerful CPU unless the decoding is done in hardware. For optimum performance, Citrix recommends that user devices have at least 2 GB of RAM and a dual-core CPU with a clock speed of 3 GHz or higher.
  • For multi-monitor access, Citrix recommends user devices with quad-core CPUs.
  • User devices do not need a dedicated GPU to access desktops or applications delivered with HDX 3D Pro.
  • Citrix Receiver must be installed.
