Product Documentation

System requirements

Apr 26, 2015

This topic lists the supported systems for the Delivery Controller, Citrix Studio, Citrix Director, and Virtual Delivery Agents (VDAs), at the time of this release. System requirements for other components, such as StoreFront, host systems, receivers and plug-ins, and Provisioning Services are described in their respective documentation; see also HDX and Desktop Lock for those feature requirements.

Unless otherwise noted, the 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 component 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, 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.

Be sure to review the Prepare to install topic before beginning the installation.

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
Requirements:
  • (For Windows 7 SP1 systems only.) Microsoft .NET Framework 3.5.1 - if using the command-line interface, you must install this manually before installing the VDA
  • (For Windows 7 SP1 systems only; other supported operating systems already have at least .NET Framework 4 by default.) Microsoft .NET Framework 4.0
  • Microsoft Visual C++ 2005, 2008, and 2010 Runtimes (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 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.

You cannot install a version 7.5 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. For more information, see the instructions for installing an earlier VDA version on those operating systems. 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:
  • (For Windows 2008 R2 SP1 systems only.) Microsoft .NET Framework 3.5.1 - if using the command-line interface, you must install this manually before installing the VDA
  • (For Windows 2008 R2 SP1 systems only; other supported operating systems already have at least .NET Framework 4 by default.) Microsoft .NET Framework 4.5.1
  • 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.

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.
