System requirements for Citrix Licensing

Mar 25, 2015

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 license servers. The Simple License Service can install licenses only on the license server where it is installed.

Operating Systems

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 2008 Family
  • Windows Server 2008 R2 Family
  • Windows Server 2012 Family
  • Windows Server 2012 R2 Family
  • Windows 7, 32-bit and 64-bit editions
  • Windows 8, 32-bit and 64-bit editions
  • Windows 8.1, 32-bit and 64-bit editions

Disk Space Requirements
