Issue Details

  • When opening a VI that utilizes functions from a LabVIEW toolkit such as the Database Connectivity Toolkit or Advanced Signal Processing Toolkit, the functions from the toolkit are missing. How do I resolve this?
  • My LabVIEW toolkit is not showing up in NI License Manager
  • When I open a VI that utilizes the LabVIEW Database Connectivity toolkit, I receive the following error message:  "The LabVIEW Database Connectivity Toolkit is expired or invalidly licensed. To purchase this product, contact National Instruments".
The message that shows up when I open my VI is similar to the following image: 


The following are troubleshooting steps to help resolve this problem:
  1. Verify that your software is installed and properly activated. You can do this by opening NI License Manager (Start Menu >> 'NI License Manager') and determining if the box or circle next to the software is green. If the color isn't green, activate the software appropriately. 
  2. If the toolkit doesn't show up in NI License Manager, navigate to C:\ProgramData\National Instruments\License Manager\Licenses and delete its associated license file which should be named similar to LabVIEW_DatabaseTK_PKG_XX0000. Then, download the toolkit from our website and install it in evaluation mode. Once complete, restart your computer and try to re-activate it from NI License Manager. If you are running on a virtual machine, reboot the entire host machine as well. 
  3. Try force reinstalling the software as it may be corrupt.
  4. If the problem still persists, please contact NI Support.
