Updated Apr 13, 2026

Environment

Software

  • Volume License Manager
  • NI License Manager

A disconnected license can be used with NI Volume License Manager (VLM) to activate NI Software from a computer that does not have access to the network.

If you are a Software Administrator and would like guidance on how to generate a disconnected license for your end user(s), please refer to the following document: Getting Started with NI VLM: Creating a Disconnected or Home License

 

If you are a user who has been assigned a disconnected license, please follow the steps below to learn how to properly set up your newly created disconnected license file.

 

1. Installing the License File: 

 

In order to install the license file, open NI License Manager from your Windows Start Menu: 

  • Drag and drop the license file into the NI License Manager window, or
  • Navigate to Options (Top Left Corner) >> Install License File and browse to the disconnected license file:

2. Verify License is Correctly Installed:

 

To verify that the disconnected license has been installed correctly and that the software is activated, open NI License Manager, navigate to the Local Licenses tab, and review the license file. The file should contain text indicating that it is a disconnected license.

Note: When you launch NI software (for example, LabVIEW), NI License Manager may display a pop‑up prompting you to license the software. To bypass this reminder, select Remind Me When They Expire.

Considerations 

 

  • Multiple License Files: While you can have multiple disconnected licenses installed. You cannot install a second license file that has the same name as an existing one. One solution is to rename the license file before installing it. 
    • Alternatively, if you want the new license file to retain the same name as a previous version, you must first uninstall the older license and then install the newer license file using the desired name.
  • Server Migration: When migrating to a new server, you will need to request a new disconnected license file from your Software Administrator in order to locally activate your software again.
  • Disconnected Licenses are backward compatible with older versions of NI software. As a result, these licenses can be used to activate the current versions included in your license agreement, as well as any previous versions.
  • Uninstalling: When you are finished using a disconnected license file, or if the license has expired, you can uninstall it by right‑clicking the license name and selecting Uninstall.
  • Client, NILM 3.7 and Prior Versions: In License Manager 3.7 and earlier, licenses will be displayed with a yellow square icon if the license is set to expire on a certain date, or a green square icon if the license does not expire. These settings were set by the Software Admin in VLM when the license file was created.
    • For an Enterprise Agreement disconnected license, the software that the license is activating will not show up green on the box next to it.
    • As long as the Disconnected License file is either fully yellow or green, the software should launch without any issues.
