Issue Details

I am using FlexNet (formerly FLEXlm) as volume license server that offers licenses to activate my NI software on the client computers. After setting up a connection to the server, the computers can open and run LabVIEW without any issue, but in the NI License Manager it shows that LabVIEW is 'unlicensed' or 'evaluation' on that computer, under both the local and network license tabs. Is this an expected behavior?


Using NI License Manager 4.x and later

This is expected behavior. Because of the way FlexNet Publisher (formerly FLEXlm) interacts with our software, you will not see an activation status in the NI License Manager for this type of license.

Using NI License Manager 3.x and earlier

Contact your company's software administrator to make sure that:
  1. The licensing request has been accepted by the Volume License Server.
  2. There are seats available on the Volume License Server for the software versions you are trying to activate. 
  3. The Volume License Server has the correct Computer ID for your computer and NI License Manager has the correct name for the Volume License Server you are trying to connect in the field shown below:
