In this article, we explain how to obtain a volume license file to begin using NI Volume License Manager (VLM). The article assumes you have successfully installed VLM on the computer where you intend to run the license server.

This article is part of the Getting Started with VLM series.

  1. License Server Computer Name
  2. Computer ID or MAC Address


For VLM 3.0 and VLM 3.1

Additional Information

You can only manage one volume license file in NI VLM at a time. If you need to merge multiple Volume License Agreements, email to get a single volume license file.

You can only use the volume license file and run VLM on the computer from which the Computer ID was generated. Using the Computer ID as a key ensures that your volume license file cannot be copied and used on another server.
