Issue Details

  • When I try to save my VI made in Windows to a previous version on my Mac computer, I receive a missing reference file error: ***VIs.llb/Get Window (Get Window Referenced file could not be found: user32.dll How can I avoid this?
  • When I move a VI made on Windows to Mac and try to save in a previous version, I see an error. How can I fix this?


This error often occurs when trying to save a VI that was built on Windows, into a previous version on Mac. Try moving the VI to a Windows computer and saving it in a previous version from there. Alternatively, you can consider posting the code on NI's Version Conversion Forums

Additional Information

The root cause here is likely that the VI is trying to use Windows Dependencies that do not exist on the Mac OS. It may require other troubleshooting if there are no Windows dependiencies here. 

Note: LabVIEW 2023 Q3 is the final release of LabVIEW for macOS. Starting with releases in 2024, LabVIEW is available on Windows and Linux OSes.
