Issue Details

I installed LabVIEW 2016 on my computer but get the error message: Unexpected Licensing Error upon launching the program. I cannot find NI License Manager (NILM) on my computer.


This error may appear when NI License Manager has not been installed on your computer. The latest version of NI License Manager can be downloaded and installed separately from other National Instruments software. Follow these steps:
  1. Ensure NI License Manager is installed 
  2. You can find frequently asked questions about activation.
  3. Make sure that you did activate all the required add ons for your application.
