Error 1026 invalid reference at runVI invoke method in main exe- subVI- subpanel

Question

Hello,
I have a main VI which have subVI's inside case structures set up to show FP when called and be modal.
These subVIs have a subpanel that will pull up a dynamicVI using RunVI invoke method.The dymaicVIs path is built using application directory constant+the VI name to the invoke method.
now the main VI is built into exe with the dynamicVIs in always included list. 
when i run the main exe i am getting 1026 error VI reference invalid. 
Plz help
Thanks

Hi Freemason,
The problem could be coming from the use of relative paths, because the path can sometimes change when building an application. Double check to make sure they are calling the right path. You can also try changing the AutoDispose Refnum in your run VI invoke node to false. It is one of the methods you can select in your run VI invoke node. If neither of these solutions work, run your code using the highlight execution function. If you implemented error handling in your program, you should be able to see the source of the error.
If you’re still having issues, could you post some screenshots or your actual VI? I may be able to get a better idea of the issue that way. I’ve also attached an example VI that uses multiple subVIs and a subpanel for reference.  Hope this helps.
