Solution
From LabVIEW 2019 onwards, the DataFinder Toolkit comes with LabVIEW by default. It is not necessary to install or repair the toolkit separately.
A couple solutions can be followed to solve this issue. If one does not work, try the other(s):
- Mass-compile the project containing the the DataFinder VIs with all dependencies. In the LabVIEW project, navigate to Tools > Advanced > Mass Compile. In the mass compile window, select the project that contains the DataFinder dependencies (VIs/library).
- Repair the LabVIEW version being used. Go to NI Package Manager >> Installed tab >> Select the LabVIEW version being used >> Repair.
