Choosing the Best Licensing Method for your LabVIEW Tools

Posted:  May 6


Congratulations! You’ve created a tool for LabVIEW and are ready to license it. National Instruments has done the legwork to offer you several well-tested options to fit your every need. The NI/ partnership offers extensive options with all sorts of flexibility and streamlines the task of licensing. We want you to get your tool(s) in the hands of users as quickly as possible, all the while using the smartest licensing toolkits available!

Select the best solution for licensing and distribution, following the guide presented below. (This guide applies to developers using LabVIEW 2010 or later).


Licensing a Library

A LabVIEW library is a set of VIs that extends the functionality of the LabVIEW editor, also referred to as an add-on. We recommend using the Third Party Licensing and Activation Toolkit (TPLAT) created by National Instruments.

If you are licensing a LabVIEW library, it is possible to require each development workstation to have a license for your library before LabVIEW will load your library in the editor. At start-up time, LabVIEW will display a list of licensed libraries along with their status, similar to the dialog below:

LabView License Status

Once a library is licensed on a development workstation, this user can export the code to a DLL, EXE, etc., and no additional licensing checks are performed (royalty-free run-time license).

TPLAT Standard Mode

If you are happy with standard licensing functionalities such as a 30-day evaluation period, requiring online activation over the Internet, and a royalty-free run-time license, then the TPLAT Standard Mode is all you need. The cost is free for LabVIEW Tools Network Partner Developers. You can centrally manage your licenses on a complimentary SoftwareKey SOLO Server1 license management account supplied by National Instruments.

TPLAT Advanced Mode

If you would like more advanced licensing control of your library, the ideal solution for you is TPLAT Advanced Mode coupled with the power of Protection PLUS 4 SDK2 (required purchase). When using Advanced Mode, you will have numerous options to customize your license parameters, including:

  • Custom evaluation periods
  • Hard evaluation date limits
  • Custom usage limits
  • Subscription-based licensing
  • Both online and offline/manual/telephone-based activation
  • Require every workstation to activate your library in addition to requiring activation of the library for use in the LabVIEW editor

Optionally, you can centrally manage your licenses using SoftwareKey SOLO Server1 (additional purchase).

Licensing an Application

Similar to licensing a library, licensing a LabVIEW application has both a standard and an advanced mode. Both approaches require purchasing a component of the SoftwareKey System.

Instant Protection PLUS 3

Tapping into thousands of lines of licensing code is quick and easy work with Instant Protection PLUS 3. Akin to a paint-by-numbers set, the step-by-step guidance of the implementation wizard will have you on your way with little to no source code changes.

You are able to protect 32-bit and 64-bit Windows executables via the easily accessible Instant Protection PLUS DLL & API. You can customize your solution from a host of options representing the most commonly requested licensing needs.

Protection PLUS 5 SDK LabVIEW Edition

For the most complex licensing needs, we are proud to announce the new Protection PLUS 5 SDK LabVIEW Edition! This is an exciting, all-new, built-from-the-ground-up addition to the SoftwareKey family of software licensing solutions. This solution consists of application programming interfaces (APIs) to give your development team complete control and flexibility over the licensing business logic and user interface. Your development team has a blank canvas and the APIs are their palette and paintbrush.

The new Protection PLUS 5 VIs make it easy to call and harness the power of the Protection PLUS 5 Native Edition library, including support for additional platforms (such as Windows, Mac OS X, and Linux — both 32-bit and 64-bit architectures) with the same API!

For a more detailed comparison between Instant Protection PLUS and Protection PLUS 5 SDK, see our blog post THE DECISION: Instant Protection PLUS 3 or Protection PLUS 5 SDK.
