Ensuring You Have the Latest License Server

Jan 09, 2012
When upgrading or installing new Citrix products, always upgrade the license server. The new license server is backward compatible and will work with older products and license files; however, new products require the newest license server to check out licenses correctly. You can install or upgrade the latest version from the product media.
Note: Citrix does not provide hotfixes for license server components and does not support older license servers with newer products. The latest versions of the license server often contain resolutions to issues appearing in earlier versions.

To find your license server version number

If you are unsure if your license server version is current, you can verify it by comparing your version with the number on the Downloads site.

On a license server with the License Administration Console:

  1. For Windows: Start the License Administration Console from the programs menu: Citrix > Management Consoles > License Administration Console.

    For License Server VPX and remote systems: Open a web browser and go to http://License Server Name:webport.

  2. Click Administration and select the System Information tab. See the release version in the information list.

On a Windows license server without the License Administration Console:

  1. Open the Registry Editor (Start > Run > regedit).
    Note: Use Registry Editor to view the license server information only. Editing the Registry can cause serious problems that may require you to reinstall your operating system.
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\LicenseServer\Install.

    The version number appears in the format: 11.5.0.0 build 9014.
