Evaluation Software With Volume License Server

Issue Details

  • I am trying to activate my software using a volume license server but in NI License Manager it still shows up as evaluation. How can I activate my software fully through the license server?
  • I have a license for specific software (i.e. LabVIEW) through a Volume License Agreement (VLA) and Volume License Manager (VLM).  My software won't connect to the license server. When I try to activate my evaluation software using a serial number in NI License Manager, I get an error that says "Invalid Serial Number. See help."  . I can launch or use the software without any problems.
  • I was previously using one of our licenses but I accidentally activated a 45 day evaluation version of LabVIEW instead of re-activating my user-based, non-concurrent seat with Volume License Manager. How do I get my computer pointed to the server again?


NI License Manager activates software based on both local and network licenses. License Manager will always look for local licenses first before referencing the server. Evaluating software creates a temporary local license that NI License Manager will reference even if a valid server license is active. When the evaluation expires or is removed, License Manager will then look to the network for an active license. 

Option 1:

Wait for the evaluation license to expire. At that point, NI License Manager will search for active licenses both locally and on the network. If a volume license server is configured correctly, the appropriate license will be pulled.

Option 2: 

Rename the evaluation license so License Manager can no longer reference it:

  1. Change the name of the evaluation licenses folder, Licenses.  You can rename the folder whatever you would like.  The file path for this folder is given below depending on your operating system:

  • Windows XP: <Program Files>\National Instruments\Shared\License Manager\Licenses\
  • Windows 7/8/10: <ProgramData>\National Instruments\License Manager\Licenses\  
  1. Reopen NI License Manager and check that your software is fully activated.

Option 3:

Try to remove and re-add the license server on the client machine:
  1. Click on the options menu in the top left-hand corner of the NI License Manager window
  2. Select Manage Volume License Servers
  3. Remove/delete the server name or address of your volume license server and click OK
  4. Click the Refresh button at the top of the screen, and close and re-start NI License Manager
  5. In the Network Licenses tab, you should now see "No volume license servers configured.
  6. Select Manage volume license servers and re-add your license server's name or address and click OK
  7. NI License Manager should re-initialize and pull the licenses from the server.


Additional Information

When you install an evaluation copy of National Instruments software, an evaluation license file is stored in the directory listed here: Where Are My Local National Instruments License Files Stored on my Computer? When you have access to the software through a different method (i.e. Volume License or Developer Suite Package), this file is not removed and hence will continue to be visible in NI License Manager.  This will not affect the functionality of the software in any way.

In some cases, the software is appearing like this because you have previously installed an evaluation copy of the software and did not activate that specific package.  For example, you have installed an evaluation copy of LabVIEW that was never activated, but then subsequently configured your computer to check out a LabVIEW or Developer Suite license through a Volume License Server.
