DataFinder Library VIs on LabVIEW broken

Updated Mar 24, 2025

Issue Details

When using any VIs from the DataFinder library in LV 2019+, they appear broken with the following error message:

Invoke Node: Bad linkage to methode information
The Invoke Node configuration on the block diagram conflicts with the method information. Right-click the node and select Relink Invoke Node to link the node with the method information.

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.
