Issue Details

When I open NI License Manager (NILM), each of the products in the list has a box or a circle next to it. These icons are colored green, yellow, red, or white. Some are shaded, half-filled or completely filled. What do these boxes mean?


The icons to the left of the product name indicate the activation status of any particular software item. Their appearance is typically a combination of the following: 
  • The different circle/square types have these meanings:
    • Full circle/square – Fully featured license
    • Half-filled circle/square – Evaluation license
    • Empty circle/square (White color) – Unlicensed
  • The different circle/square colors stand for:
    • Green color – Non-expiring license
    • Yellow color – Fully featured expiring license. This can also refer to a disconnected license .
    • Red color – Expired license
    • Faded – Will prompt to activate on next launch of the activation wizard
  • There are two special icons:
    • Red Exclamation Mark – Corrupted license or requires reactivation
    • Yellow Question Mark – Activated on another computer ID


With NI License Manager 4.0 the icon appearance was reworked.
In License Manager 4.0 and newer they look like this:


For License Manager 3.7 and earlier:


In this License Manager 3.7 screenshot, the icons have the following meanings:
  • LabWindows™/CVI Full Development System 2013 is an evaluation license that has expired meaning that the software is still installed but disabled until a new license is applied to it.
  • DIAdem Advanced Edition 2015 is activated or otherwise fully featured, with an expiring license. This can also refer to a disconnected license.
  • DIAdem Professional Edition 2015 is activated or otherwise fully featured, non-expiring license upon the next launch of DIAdem.
  • LabVIEW 2015, and Signal Express 2015 are activated or otherwise fully featured, non-expiring licenses.
  • LabVIEW Professional Development System 2016 is an expiring evaluation license.
  • TestStand Development System 2016 is a corrupted license.
  • The LabVIEW Base Development system as well as many others are unlicensed products or products being served from a network license server.  Launching it will prompt the user to activate the software, resulting in one of the described color status indicators.
