Issue Details

I am getting an error from an imported LabVIEW VI that says: "This VI or item belongs to a library that is expired or invalidly licensed. Activate the license of the library to edit or run the VIs and items the library owns. For more information on activating this VI or item's owning library, see the error message on the VI or item's library."

The message that shows up when I open my VI is similar to the following image:

Solution

Go through the following troubleshooting steps to fix this issue:
1. Verify that the toolkit or library the VI is part of is correctly installed and activated by using the NI License Manager. If the toolkit does not show as activated proceed with licensing it by following the steps on the following article: Activating NI Software Products.
2. If the toolkit the VI is part of is already licensed, check if there are any requirements for a specific development system. You can do this by doing a back search of the LabVIEW class and VIs in the LabVIEW Help Document. If a specific version of the development system is needed, activate it using the NI License Manager.

3. If the issue persists after licensing the development system and the toolkit, try repairing or re-installing the toolkit.
