  • I am unable to activate my software using a volume licensing server.

Solution

Refer to the sections below for different potential causes and steps to solve this issue.


Incompatible License File Version

Always use the most recent license file to make sure you have access to the newest versions of the software. A license file can be outdated if you have upgraded your software and NI VLM is still using an older version of the license file.

The software administrator should:
  1. Ensure that the licenses displayed in the Licenses view in License Manager is up to date and matches the software version. The license file currently used by NI VLM can be found in the following file path: C:\ProgramData\National Instruments\Volume License Manager\nivlm.lic.
For example, if LabVIEW is licensed up to 2017 SP1 but LabVIEW Application Builder is only licensed up to 2017, Application Builder will not work in LabVIEW 2017 SP1.
  1. If the license file is not up to date, send an email to agreements@ni.com to request for an upgraded license file. Include the following information: administrator name, administrator email, company name, and Service ID.
  2. (Recommended) Create a back-up of the current server.
  3. Install the upgraded license file in NI VLM.
  4. Click Apply Changes.
  5. Restart the license server.
If you are unsure about your eligibility to activate newer software versions, contact NI for clarification. 


Incompatible NI VLM Version

NI License Manager 4.4 or later is incompatible with NI VLM 3.1 and previous and FlexNET Publisher versions older than 11.15.

The software administrator should:
  1. Check what NI VLM and NI License Manager version the license server is running.
  2. If the NI VLM version is incompatible, upgrade it to NI VLM 3.1.1 or later. If your software administrator is running the FlexLM/FlexNet Publisher, they will need to upgrade the vendor daemon to version 11.15 or later.
Note: NI VLM 3.1.1 and later and FlexNET Publisher 11.15 and later are compatible with all previous versions of License Manager. Upgrading VLM will not affect clients with versions of NI License Manager older than 4.4. 
 

License Server is Down

The software administrator should:
  1. Check that the server computer is on and the license server is still running in NI VLM.
  2. If the license server is stopped, navigate to Tools»Start Volume License Server. 

If you experience issues, refer to Unable to Start License Server When Using NI VLM for more steps.


Firewalls on Server Side is Blocking Client-Server Communication

Ensure the firewall on the server is not blocking the specified ports (default is 27000 and 4637).

The software administrator should:
  1. (Optional) Temporarily disable the firewall for testing.
  2. Configure firewall to allow incoming connections on the specified ports.


Incorrect Permissions

The software administrator should ensure that the client has the appropriate permissions or is added to the appropriate group for the software that is not working. After making changes to permissions, click the Apply Changes button.


Client Not Connecting to Server

The client should:
Note: If your volume license server is running on a port other than 27000, ensure that the port number is included with the server name (server:<port number>).
  • Remove the server information to force NI License Manager to look at local licenses. Then, add the server and port information again.
  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, then 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.

Refer to Unable to Communicate With License Server Error in NI VLM for additional steps.

 

Check Debug Log

If any of these steps failed, the software administrator should:
  • Check the NI VLM debug log. The log will confirm if the client attempted to checkout a license and whether the attempt was successful.

If the debug log shows the client failing to check out a license, confirm the following:  

Concurrent Unmanaged Licenses

If you are using concurrent unmanaged Licenses, the activation status under Network Licenses remains default grey even If you have access to them. This is a purely cosmetic issue and should not prohibit your access to the software. For more information, refer to Unable to Activate Software Using Concurrent Unmanaged Network Licenses
