Product Documentation

System requirements

Mar 19, 2015

This document lists the supported systems for the Delivery Controller, Citrix Studio, Citrix Director, and Virtual Delivery Agents (VDAs), at the time XenDesktop 7 released.

System requirements for other features and components, such as StoreFront, host systems, HDX, receivers and plug-ins, Desktop Lock, and Provisioning Services are described in their respective documentation.

Unless otherwise noted, the installer deploys component prerequisites automatically. This includes .NET 3.5 SP1, which is required when installing components on Windows 7 or Windows Server 2008 R2 systems.

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

If you install all the core components (Controller, 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.

Virtual Delivery Agent (VDA) for Windows Desktop OS

Supported operating systems:
  • Windows 8, Professional and Enterprise Editions .
  • Windows 7 SP1, Professional, Enterprise, and Ultimate Editions.
The installer automatically deploys the following requirements, which are also available on the Citrix installation media in the Support folders:
  • (For Windows 7 systems only.) Microsoft .NET Framework 3.5.1 - if using the command-line interface, you must install this manually before installing the VDA.
  • Microsoft .NET Framework 4.0.
  • Microsoft Visual C++ 2010 Runtime (32-bit or 64-bit, depending on platform).

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 where 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 7 and Windows 8 editions, the 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.

You cannot install a Version 7.0 VDA supplied with this release 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. For more information, see Install an earlier Virtual Desktop Agent on Windows XP or Windows Vista. Remote PC Access is not supported on Windows Vista operating systems.

Virtual Delivery Agent (VDA) for Windows Server OS

Supported operating systems:
  • 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:
  • (For Windows 2008 R2 systems only.) Microsoft .NET Framework 3.5.1 - if using the command-line interface, you must install this manually before installing the VDA.
  • Microsoft .NET Framework 4.0.
  • 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 where 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 2008 R2 and Windows Server 2012 editions, the Media Foundation feature is installed through the Server Manager (for Windows Server 2012: ServerMediaFoundation, for Windows Server 2008R2: DesktopExperience). However, N editions do not include certain media-related technologies; you can obtain that software from Microsoft or a third party.

The Print Spooler Service is enabled by default on the Windows server. If you disable this service, you cannot successfully install a VDA for Windows Server OS. Therefore, ensure that this service is enabled before installing a VDA.
