System requirements

NOTE:

Learn about product name changes here.

Introduction

System requirements components that are not covered here (such as StoreFront, Citrix Workspace app, and Citrix Provisioning) are described in their respective documentation.

For product components and features that you can install on Windows Servers, Server Core and Nano Server installations are not supported, unless specifically noted.

For globalization information, see CTX119253.

Specific recommendations for sizing VMs that deliver desktops and applications cannot be provided because of the complex and dynamic nature of hardware offerings. Every deployment has unique needs. Generally, sizing a Citrix Virtual Apps VM is based on the hardware and not the user workloads (except for RAM; you’ll need more RAM for applications that consume more). The Citrix VDI Handbook and Best Practices contains the latest guidance on VDA sizing.

Remember: In a Citrix Virtual Apps and Desktops service deployment, you don’t need to install or manage the core components (Delivery Controllers, the site database, Studio, and Director).

Virtual Delivery Agent (VDA) for Desktop OS

Supported operating systems:

  • Windows 10
    • For edition support, see CTX224843.
    • For Citrix known issues with version 1709, see CTX229052.
    • Desktop composition redirection and legacy graphics mode are not supported on Windows 10.

Requirements:

  • Microsoft .NET Framework 4.7.1 is installed automatically, if it (or a later version) is not already installed.
  • Microsoft Visual C++ 2013 and 2015 Runtimes, 32- and 64-bit.

Remote PC Access uses this VDA, which you install on physical office PCs. This VDA supports Secure Boot for Citrix Virtual Desktops Remote PC Access on Windows 10.

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 supported Windows desktop OS 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.

For Linux VDA information, see the Linux Virtual Delivery Agent articles.

To use the server VDI feature, you can use the command line interface to install a VDA for Windows Desktop OS on Windows Server 2016. See Server VDI for guidance.

For information about installing a VDA on a Windows 7 machine, see Earlier operating systems.

Virtual Delivery Agent (VDA) for Server OS

Supported operating systems:

  • Windows Server 2019, Standard and Datacenter Editions
  • Windows Server 2016, Standard and Datacenter Editions
  • Windows Server 2012 R2, Standard and Datacenter Editions

The installer automatically deploys the following requirements:

  • Microsoft .NET Framework 4.7.1 is installed automatically, if it (or a later version) is not already installed.
  • Microsoft Visual C++ 2013 and 2015 Runtimes, 32- and 64-bit.

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

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 versions, the Media Foundation feature is installed through the Server Manager. However, N editions do not include certain media-related technologies; you can obtain that software from Microsoft or a third party.

If Media Foundation is not present on the VDA, these multimedia features do not work:

  • Flash Redirection
  • Windows Media Redirection
  • HTML5 Video Redirection
  • HDX Realtime Webcam Redirection

For Linux VDA information, see the Linux Virtual Delivery Agent articles.

For information about installing a VDA on a Windows Server 2008 R2 machine, see Earlier operating systems.

For VDAs for Windows Server OS, user authentication during printing operations requires the Universal Print Server to be joined to the same domain as the VDA.

Standalone client and server component packages are also available for download.

For more information, see Provision printers.

Other

StoreFront 3.0.1 is the minimum supported version with this release. To use the zone preference feature, you must be using minimum StoreFront 3.7 and Citrix Gateway (formerly Netcaler Gateway) 11.0-65.x.
