    The License File

    The Qube! license file contains the keys for both the Supervisor and Worker, and:

    • Must be installed on the supervisor. The location is documented later on this page - see Installing Licenses by Hand

    • Must be named qb.lic

    Qube! license keys can be installed either with the WranglerView utility Qube! UI or creating and editing the license file by hand.  License file updates take effect immediately, there is no need to restart the Supervisor or Workers. 

    Installing with Qube!



    The simplest way to install the Qube! license is with the WranglerView utilityQube! UI, via the Admin Administration-> Install license >Install license on (Local) Supervisor menu item.  This option is greyed out if you are not on the Supervisor.


    Windows users: you must start WranglerView the Qube! UI with "Run as Administrator", even when you are logged in as an admin-equivalent or local administrator. This is due to Window's "elevated privileges" security policy.

    A dialog will appear, prompting you to copy & paste your license strings.  You have the option of either adding the keys to your existing licenses or overwriting replace the license file.

    Please note that the license string does not include "------------- < snip - do not include this line in the license file > -------------" lines that are in your license email.

    Installing Licenses by Hand

    You can also install license keys by editing the license file directly.  

    • Make a backup copy of the license file before editing it.
    • You must use a text editor capable of saving out plaintext.
    • The license file must end with the extension ".lic".
    • Saving the license file with a .rtf, .txt, .doc, extension or in any format other than plaintext will render your license file invalid.

    License file location

    Depending on the supervisor's operating system, the qb.lic file is located in:

    • Linux & OSXmacOS:                 /etc/qb.lic
    • Windows XP, XP-64, Win2K3:    C:\Windows\qb.lic
    • Windows Win2K8, Vista, Win7:   C:\ProgramData\Pfx\qube\qb.lic

    Verifying License Installation



    the Qube! UI

    Immediately after installing the license, the WranglerView Qube! UI title bar should update and reflect the new license count.

    By Command-line

    You can verify the license count with the qbping utility. In this example, all worker licenses for this supervisor will use metered licenses.

    jburk-15-mbPro:LaunchAgents jburk$ qbping

    supervisor - active - tag: 78:4F:43:68:FD:7C 7.0-1c rel-7.0-0006 osx - - host - 0/0 unlimited licenses (metered=0/300) - mode=0 (0).

    The license counts displayed can be interpreted in the following manner:

    • 0/0 unlimited licenses: 0 licenses in use, 0 worker licenses installed

    • metered=0/300: metered licensing is enabled and in effect, currently using 0 licenses of a maximum of 300 metered worker licenses

    "I have 0 licenses now..."

    If after license installation you now show 0 licenses, you haven't yet installed the worker keys, or the license file has become invalid (perhaps it got saved out with an extension other that .lic, or saved in RTF or Wordpad format). Check the license file with a plaintext editor

    Optionally, setup Metered Licensing

    You can run a supervisor without any worker licenses if you have setup Metered Licensing. See Getting Started with Metered Licensing
