The system requirements in this document were valid when this product version released. Updates are made periodically. System requirements for components not covered here (such as host systems, Citrix Workspace app, and Citrix Provisioning) are described in their respective documentation. Show
Review Prepare to install before beginning an installation. Except where noted, the component installer deploys software prerequisites automatically (such as .NET and C++ packages) if the required versions 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. For globalization information, see Knowledge Center article CTX119253. For components and features that can be installed on Windows Servers, Nano Server installations are not supported, unless noted. Server Core is supported only for Delivery Controllers and Director. Hardware requirementsRAM and disk space values are in addition to requirements for the product image, operating system, and other software on the machine. Your performance varies, depending on your configuration. Your configuration includes the features that you use, plus the number of users, and other factors. Using only the minimum can result in slow performance. The following table lists the minimum requirements for core components.
Sizing of VMs that deliver desktops and applicationsSpecific recommendations cannot be provided because of the complex and dynamic nature of hardware offerings, and every deployment has unique needs. Generally, sizing a Citrix Virtual Apps VM is based on the hardware and not the user workloads. The exception is RAM. You need more RAM for applications that consume more. For more information: Microsoft Visual C++When installing a Delivery Controller, Virtual Delivery Agent (VDA), or Universal Print Server, the Citrix installer automatically installs the Microsoft Visual C++ 2015-2022 Redistributable.

The recommended optimal screen resolution for viewing Director is 1366 x 1024. Virtual Delivery Agent (VDA) for single-session OSSupported operating systems:
Requirements:
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 11 and 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 are not installed and do not work. Do not remove Media Foundation from the machine after installing the Citrix software. Otherwise, users cannot log on to the machine. On most supported Windows single-session 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 more information, see Prepare to install. 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 single-session OS on a supported Windows Server machine. 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 multi-session OSSupported operating systems:
The installer automatically deploys the following requirements, which are also available on the Citrix installation media in the Support folders:
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 are not installed and do 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. For more information, see Prepare to install. If Media Foundation is not present on the VDA, these multimedia features do not work:
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. Hosts / virtualization resourcesThe following host/virtualization resources (listed alphabetically) are supported. Where applicable, the major.minor versions are supported, including updates to those versions. Knowledge Center article CTX131239 contains current version information, plus links to known issues. Some features might not be supported on all host platforms or all platform versions. See the feature documentation for details. The Remote PC Access Wake on LAN feature requires Microsoft System Center Configuration Manager minimum 2012. Supported hypervisors: Supported public cloud hosts: When adding public cloud host connections to your deployment, consider the following:
Active Directory functional levelsThe following functional levels for the Active Directory forest and domain are supported:
HDXAudioUDP audio for Multi-Stream ICA is supported on Citrix Workspace app for Windows and Citrix Workspace app for Linux 13. Echo cancellation is supported on Citrix Workspace app for Windows. See the specific HDX feature support and requirements. For more information on HDX features and Citrix Workspace apps, see the Feature matrix. The following clients are supported for Windows Media client-side content fetching, Windows Media redirection, and real-time Windows Media multimedia transcoding: Citrix Workspace app for Windows, Citrix Workspace app for iOS, and Citrix Workspace app 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 or Choose defaults for this program. GPU transcoding requires an NVIDIA CUDA-enabled GPU with Compute Capability 1.1 or higher; see https://developer.nvidia.com/cuda/cuda-gpus. HDX 3D ProThe VDA for Windows single-session OS detects the presence of GPU hardware at runtime. The physical or virtual machine hosting the application can use GPU Passthrough or Virtual GPU (vGPU):
