VI has an Error of Type 4E748

Issue Details

I built an executable but I get the following error: VI has an error of type 4E748. The full development version of LabVIEW is required to fix the errors.


This is probably caused by a bad linkage in your LabVIEW project and you will need to perform a mass compile.

Additional Information

When mass compiling, LabVIEW opens and closes VIs automatically. This does the following:
  • Ensures that all subVIs exist and relinks them to the main VI. It decreases loading time since LabVIEW will not need to search for the VIs.
  • Updates the VIs to the current LabVIEW version.
  • Reports corrupted VIs which can prevent them from loading correctly.
