Issue Details

I'm working to improve my class structure in LabVIEW OOP but after a few changes I can no longer access my class properties in my project and get error 1003 at What do I do to fix this?


You can locate this at the directory below. This location will depend on your version and bitness of LabVIEW (This example uses LabVIEW 2017 32-bit):
C:\Program Files (x86)\National Instruments\LabVIEW 2017\resource\Framework\Providers\VILibrary

Open up the and press the broken run arrow to see what errors exist. 

If the VI is unable to locate specific files and dependencies, Browse for them and re-link them to the VI having the problems. After these paths have been re-linked, go back to your project and right click your Class >> Properties. The issue should no longer persist.
