Issue Details

I am developing an NI-DAQmx application in LabVIEW 2019 on a Windows 10 computer. The application works fine in the development environment as all the DAQmx VIs can be found and the code shows a clean arrow. However, when the application is built into an executable, it comes up with a broken arrow. Also, all of the DAQmx VIs are missing when I debug the executable.

Solution

This behavior suggests a possible corruption of the LabVIEW or NI-DAQmx software installation in your computer. Follow the troubleshooting steps below to solve the problem.
  1. Make sure you are using a compatible version of NI-DAQmx. If needed, download and install a supported version of NI-DAQmx.
  2. Check if the issue persists with other NI-DAQmx applications to identify if the behavior is related to a specific project.
  3. Repair the NI-DAQmx driver using the NI Package Manager (NIPM).
  4. Uninstall and reinstall LabVIEW and NI-DAQmx using NIPM.
