Licensing Overview

Licence types

In Insight, there are two types of licences that are available:

  1. Node-locked licence, which is fixed to a single computer.
    • Activating a node-locked licence will bind it to a particular computer.
    • As such, node-locked licences are intended for use by a single person at a time.
    • For multiple users on a single machine, each user is required to activate the licence separately.
  2. Floating licence, which may be installed on multiple computers, but only used by one user at a time per licence.
    • An active internet connection is required to activate and use a floating licence.
    • For a shared resource that allows multiple logins using systems like Citrix, VNC, or remote X-Windows sessions, a token with floating licences must be purchased.
    • If you purchase multiple licences, you may receive a single token that you can activate multiple times. Activating a floating licence tells Insight which pool of licences to use on this computer.
    • If multiple users run the software on a single machine, they will each need to activate the token (see How do I activate floating licence for many users?).
    • Every instance of Insight consumes a floating licence. Hence, opening multiple projects on a single machine will occupy multiple floating licences.

Activating and viewing licences

If you are on the fence about whether to purchase DUG Insight, you can choose to trial Insight with an evaluation licence. For more information on the limitations of an evaluation licence, and steps to request for an evaluation licence, see Obtaining an Evaluation Licence.

Whether you are purchasing or evaluating Insight, you will receive a licence token via email upon a successful request. There are two ways to activate the licence token:

  • Online Activation — Online activation requires an active internet connection.
  • Email Activation — Alternatively, if you do not have direct internet access, you can activate your Insight licence via email.

You can view your license(s) from the Licence Manager (see Viewing Licences) after activation.

Node-locked licences and working off-line

For travel and when working in areas with limited connectivity, we recommend using a node-locked licence. Contact if you have floating licences and would like to arrange a temporary node-locked licence for travel purposes.

During activation, details about the computer are combined to generate a unique key. This key is sent to the DUG licensing server and registered with the licence. If an internet connection is available, this is done automatically, but manual activation is possible via email if connectivity is limited (contact for more details).

After activation, an internet connection is not required to use the licence.


If you are unable to connect to our server to validate your licence token online, your network could require a proxy to access the web. See Configuring Proxy Settings to access and configure your network.

If you need to configure the firewall, see Firewall Configuration.
