My VI Is Not Loadable When Opened in a Newer LabVIEW Version

  • LabVIEW Application Builder Module
  • LabVIEW Base

Issue Details

I am trying to:​
  • Open my own code in a newer LabVIEW version
  • Install or use a 3rd Party Toolkit made for a previous LabVIEW version 
I am getting the following error:


If you or your company created the code:
  • Find the source code. 
    • There will be a LabVIEW project with a source distribution like the following:
  • The VIs listed within this project will still have their block diagrams, so just grab the one(s) you need
    • You can navigate to a VI's location on disk by right clicking the VI>>Explore...
If the code was created by a 3rd party:
  • If a matching version of the toolkit is available, use that instead
  • Try to contact the developers of the toolkit to see if they can upgrade it for you
  • Note: Without access to the source code, the VI cannot be upgraded to a new LabVIEW version
    • Thus, NI cannot help with upgrading 3rd party toolkits that have VIs with their block diagrams removed

Additional Information

When block diagrams are removed, users cannot edit the VI, move the VI to another platform, or upgrade the VI to a future version of LabVIEW.  See Removing Block Diagrams from VIs for additional details.
