Issue Details

I can't deploy my LabVIEW code to my Real-Time target, I get a message saying that one of my VIs was loaded with errors on the target and was closed.

The error may take the following forms:

[LIBRARY NAME].lvlib:[YOUR VI NAME].vi loaded with errors on the target and was closed.

Deploying [YOUR VI NAME].vi [YOUR VI NAME].vi loaded with errors on the target and was closed.

Solution

If you recently upgraded versions of LabVIEW, your VIs may need to be recompiled to run properly on your target. Follow the steps in Forcing a VI to Recompile to do this.

If LabVIEW has not been upgraded and this error appeared after making changes to your code, this issue can often still be corrected by force-recompiling your VIs. If that does not change the behavior, you can attempt to resolve this by clearing the object cache in LabVIEW in order to ensure that everything is recompiled before deployment. There are two ways to do this:
  • In LabVIEW, go to Tools >> Advanced >> Clear Compiled Object Cache.
  • Delete the following file: C:\Users\<USERNAME>\Documents\LabVIEW Data\VIObjCache\<VERSION>\objFileDB.vidbe on disk.
