Issue Details

  • I am unable to activate my volume licensing software using my licensing server in NI License Manager 4.4.
  • I recently upgraded NI software. Now I am no longer able to activate my software using the volume licensing server.
  • My software is in evaluation mode and can't check out the license from the volume license server in License Manager 4.4. How can I fix this?
  • Software shows as licensed in Network Licenses in NI License Manager but opens in evaluation mode


NI License Manager 4.4 is incompatible with NI Volume License Manager (VLM) versions 3.1 and previous. 

Ask your licensing software administrator to update to version 3.1.1 or later of NI Volume License Manager. NI VLM 3.1.1 and newer is compatible with previous versions of NI License Manager. 
If your software administrator is running the FlexLM/FlexNet Publisher, they will need to upgrade the vendor daemon to version 11.15 or newer.

Note: Volume License Manager 3.1.1 and later are compatible with all previous versions of License Manager. Upgrading VLM will not affect clients with versions older than 4.4. 

Additional Information

NI License Manager 4.4 uses a new version of the Flexera licensing technology that makes it incompatible with older versions of NI Volume License Manager.
