Qube has both Supervisor and Worker license keys

    You'll have only one supervisor key, but can have any number of worker keys.

    Qube has a single license file for all license keys

    Qube has license keys for both the Supervisor and the Workers, but the keys for both are installed on the supervisor.

    • you can have only a single supervisor license key in your license file.
    • you can have any number of worker license keys in your license file, they will be added together.

    Without a license file, the supervisor will not dispatch jobs


    New in Qube 6.10

    Prior to Qube 6.10, a supervisor would dispatch jobs on up to 2 hosts, but now a license file is necessary in all cases.

    License keys are valid for the major.minor Qube version they are issued for, and ALL versions before that


    Do not upgrade your supervisor to a newer major.minor until you have installed the license key for the newer version. Failing to do so will result in your supervisor refusing to dispatch jobs until you either install the updated license keys or downgrade your supervisor.

    License keys are issued for a particular version of Qube.  A key for a version ahead of your current version will work, but you can't use an older key with a newer version.

    • a key for 6.9 is valid for any version of 6.9-x (6.9-0, 6.9-2, etc), and any version before 6.9 (6.8-x, 6.7-x, etc)
    • a key for 6.9 is invalid for 6.10-0 and onwards.

    Types of Supervisor Licenses

    PipelineFX currently supplies two types of Qube! supervisor licenses for Qube!; these licenses affect how man job instances the supervisor will send to each worker:

    • Unlimited - These licenses will allow you to put any number of any kind of job onto a single Worker at the same time. You need one per Worker.
    • Designer - The single restriction Designer licenses have is that they will only allow a single instance of a job on a Worker at one time. They are intended for use in studios where the primary application being used does not support running more than one job on a host, such as Adobe After Effects and Autodesk 3ds Max. The PipelineFX website has an FAQ about Designer licenses.

    You cannot mix license types on a network - all the Workers must have one type or the other. If there is a mixture installed, they all fall back to Designer licenses.

    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 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! WranglerView

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


    Windows users: you must start WranglerView 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 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 will be invalid.

    License file location

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

    • Linux & OSX:                 /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

    With WranglerView 

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

    By Command-line

    You can verify the license count with the qbping utility.

    jburk-15-mbPro:LaunchAgents jburk$ qbping
    supervisor - active - tag: 14:10:9F:E3:70:FD 6.4-4 bld-custom osx - - host - 0/10 licenses.

    The license count displayed here means: "0 of 10 licenses in use".

    "I only have 2 licenses now..."

    If after license installation you now show only 2 licenses, this means that your license file was either saved in the wrong format, with the wrong name or extension, or had invalid data added to it.  Restore your original license file (you made a backup copy beforehand, right?), and try again.
