  • Volume License Manager

Issue Details

My evaluation license is causing a conflict with my volume license. I need to access my local National Instruments license files in order to remove evaluation licenses, hide my local licenses or to troubleshoot an issue with National Instruments support.  Where are these files located in Windows?

Solution

For NI License Manager 4.0: Local licenses are required to access software through a Network License from a VLM server, even if the local licenses are in Evaluation or Unlicensed status.

  1. The current best method is to add the server using Access Volume License Server from a Client Machine, NI License Manager should read this as a higher priority than the local licenses.
  2. After adding the server to NI License Manager, check with your software administrator to see if you have the necessary user permissions to access software through the server.
  3. If software still shows in Evaluation, wait for the evaluation to expire. NI License Manager should then find the network license and activate software from the server.
  4. In the event that you are dealing with a temporary activation code provided by NI, right-click on the expiring license and select "deactivate"


For NI License Manager 3.7 or Earlier: Local licenses are not necessary to access licenses from a VLM server. National Instruments software local licenses can be moved from the following directories:

Windows XP<Program Files>\National Instruments\Shared\License Manager\Licenses\
Windows 7/8/10<ProgramData>\National Instruments\License Manager\Licenses\

Be sure to create a backup before deleting any files in this location.

Note: <ProgramData> is a hidden folder in Windows 7 and Windows 10. Please see  Show Hidden Files to show hidden files in Windows 7 and 10.

Another method to verify full activation is hiding the local licenses folder from NI License Manager. To do this create a new folder within the Licenses folder, then move all license files inside of it. This ensures that all licenses are still on your system, but in a location that NI License Manager does not check. 

Additional Information

One common use case for hiding the license file is verifying that your National Instruments software is fully activated by hiding an evaluation license for the same product, as the evaluation license will show over the full license.

20-digit activation/evaluation codes from National Instruments cannot be used while the license file for the product in question is hidden.
