Why does Build Application vi work in development environment but not in executable; error 1025

Hello,

I have an application ("A") that I am trying to build using another application ("BuildA").

I can create an application for A manually from its project using the Build Specification, and it works fine (A.exe).

Also, when I run BuildA.vi in the development environment it calls the "Build.vi" correctly and again builds application A.exe just fine.

Then, when I make BuildA an application (manually) and run BuildA.exe, I would expect it to also create A.exe just like BuildA.vi did in the development environment.

However, it fails with the error:

Code: 1025

Open VI Reference in NI_App_Builder_API.lvlib:Build (path).vi->BuildA.vi<APPEND>
VI Path: <b>C:\TEMP\AppBuild\BuildA\vi.lib\AppBuilder\BuildTarget.vi</b>

I noticed this thread , which looks like a similar problem, but no conclusion was reached.

Why does BuildA.vi work fine in the LabVIEW environment, but the application BuildA.exe does not work?  All paths are hard-coded, so it shouldn't be a path issue.

Thanks,
