System requirements

Aug. 03, 2016

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

Important: Review Prepare to install 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.

Important: After you install XenApp 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.
