LabVIEW Error: "VI Is Not Loadable" When Opening in Newer Versions

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: 

"LabVIEW: VI is not loadable. 

In a built application, this error might occur because the VI being loaded was last compiled for a different OS or with CPU features, such as SSE, that this target does not support. In this case you must rebuild the application for the target OS and make sure SSE compiler settings in the build specifications match the target platform. This error also might occur if the VI is a polymorphic VI, which cannot be loaded in the LabVIEW Run-Time Engine. You must load an instance of the polymorphic VI instead of the polymorphic VI itself. 

An error occurred loading VI ''. LabVIEW load error code 11: VI version (15.0) cannot be converted to the current LabVIEW version (17.0) because it has no block diagram."

The error message can look similar to the one below:


This error occurs when the developer of a VI has removed the block diagram. Depending on whether the developer is 3rd party, there are a few different ways to resolve this error.

If you or your company created the code:
  • Find the source code. There will be a LabVIEW project with a source distribution, similarly to the image below:
  • The VIs listed within this project will still have their block diagrams, so use the one(s) that are required. You can navigate to a VI's location on disk by right-clicking the VI >> Explore...

If the code was created by a third 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. Their product pages often have contact info provided, for example, PDF Toolkit for LabVIEW - Carya Automatisering provides an email in the Overview section
  • Reinstallation of the 3rd party software solves this issue if the error is shown when the toolkit is already installed. 

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.
