packed library version compatibility issue

[jmountney]

Why can't LabVIEW open VIs from a packed library created with an earlier version of LabVIEW?

[Sam_Sharp · Accepted solution]

A packed project library essentially contains only compiled code so, like an executable, it has to be run with the same major version of the run-time engine that it was built in.

You might want to look at creating a LabVIEW DLL from your code, you should be able to call that in a newer version of LabVIEW providing you have the correct version of the runtime engine installed? (I've never tried it but that's my understanding anyway)
