Software

  • LabVIEW
  • LabVIEW Professional
  • LabVIEW Full
  • LabVIEW Base

Issue Details

  • I have a VI created in LabVIEW 32-bit or LabVIEW 64-bit, and I want to know if I can open or run it in the other version.
  • When I try to move my VI between versions, I am unsure if it will execute correctly or if there are compatibility limitations.

Solution

Yes, a VI that is written with LabVIEW 64-bit development system can be opened in LabVIEW 32-bit and vice versa because the code is not compiled until the VI is run or saved.

Additional Information

The VI source code is portable, but execution depends on the availability of compatible dependencies.
Executables (EXEs) are not interchangeable between 32-bit and 64-bit systems without rebuilding for the target architecture.
