Issue Details

I'm 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."

It's possible that subVI's in this VI are part of a toolkit, or development version that you don't have. Back search the LabVIEW class and VI's in your version of the LabVIEW User Manual, and see what toolkit it's part of, or if there are requirements for a certain development system.

Then check NI License Manager to see if you have this toolkit or requirement activated.
