System requirements for Citrix Licensing

Aug 14, 2017

Requirements for Licensing for Windows

Citrix Licensing is compatible with the same hardware required to support the compatible operating systems. No additional hardware is required.

Note

  • The license server does not support multi-homing (two network cards plugged into distinct networks).
  • The License Administration Console manages the License Server on the computer on which it is installed. It cannot manage remote or third party License Servers. The Citrix Licensing Manager can install licenses only on the License Server where it is installed. We recommend installing the License Server on server operating systems only. The consoles can be accessed from any server or client operating system using a web browser. License Servers cannot communicate with each other.

Operating system

You can install the license server on servers running the following Microsoft operating systems. Citrix recommends that you install the latest Microsoft Service Pack and updates.

  • Windows Server 2016 Family
  • Windows Server 2012 R2 Family
  • Windows Server 2012 Family
  • Windows Server 2008 R2 Family
