Issue Details

When loading my project in LabVIEW 2017 or LabVIEW 2017 SP1, it freezes when regenerating the channel wire instances of my VIs.


Use the Task manager to quit LabVIEW, and open again the project. Try the next troubleshooting steps:

  1. Opening smaller VIs that use Channel Wires, so LabVIEW can regenerate them correctly, and open the Main VI later, so the channels required are generated beforehand.
  2. Open the Main VI again and repeat the process if it freezes.

Additional Information

With projects/VIs that contain many Channel Wire instances, LabVIEW may freeze when regenerating every single one of them.
