Issue Details

I have installed a disconnected license file using NI License Manager and receive no warnings during installation. However, when I launch my software, it is still not activated.


First, open NI License Manager to locate and check the activation status of the disconnected license . If you are using NI License Manager 4.0 or later, the disconnected license will be the first item in the Local Licenses tab.

If the status indicates a fully featured license.

  • If you still get the activation window when trying to launch the software, check that the software version you are trying to activate is the same or previous than the one your license activates, if you have a more recent version of the software you will need to ask your software administrator for a new and updated disconnected license to activate it.
  • If the activation wizard indicates the software is in evaluation after installing the disconnected license. Refer to VLM Disconnected License File Showing up as Evaluation .

If the status shows a red exclamation mark for NILM 3.7 or unlicensed (gray status) for versions 4.0 and later.

There may be a difference between the username/computer name settings on the computer.
  • For computer-based licenses, ensure that the computer name for which the disconnected license file was generated matches the computer name of the target machine. To find the computer name of your machine, go to the command prompt and type 'hostname', then click enter. 
  • For user-based licenses, ensure the username provided during the disconnected license file generation matches the username on the target machine. To determine the current username of the machine, open up a command prompt window and enter echo %username%.
    • If the computer is on a different domain than the server, be sure to include the domain when generating the license file. You can determine the full username (with domain) by entering whoami into the command prompt.
    • If the username of the target machine is different than the one of the disconnected license file, you need to ask the software administrator to change the username of the disconnected license file to make it match with the username of the machine. You can also change the username of the machine matching the one of the disconnected license file.
If the above steps do not resolve the issue, try uninstalling then reinstalling your NI software .
