Save Without Diagram Breaks VI

[paul_cardinale]

I have a VI with a lot of dependencies. The VI and it's dependencies are saved with LabVIEW 2018. Using LV2018, I save a secure version of the VI without it's block diagram.  It works fine under LV2018, but of course it won't work under LV2019.   So using LV2019, I save a secure LV2019 version without it's block diagram. But when I load that version (using LV2019), it's broken. Apparently something in the secure version needs to be compiled (but of course it can't be recompiled).  How do I figure out what?  How do I make the "Save" without diagram yield a non-broken version?

These VIs illustrate what I'm trying to do.

"Create Secure Version.vi" was used to create "Main - secure 2018.vi" and "Main secure 2019.vi"

In this simple case, everything works fine, but my real app, the secure 2019 version is broken.
