Testing Windows Build Runtime Error

I am using a Window Resize Plugin. I got everything to work in Windows with the debug all the way to creating and testing the build with 3 different windows resizes. I’m using Setup Factory for the installer and I have been creating perfect running versions without the re sizing plugin.

When I’m testing the full build in Windows 7 and 8.1. It installs ok, but when I execute the program I’m getting a Run time Error

Common\Plugin.cpp 5503
(entrypointName, out) can’t find plugin method XMLXsitHandler._init

I don’t have a clue what this error means in Windows (C++ and XML File ???) . Does anyone know what this run time error is. Is it something from a setting in the installer?

maybe a dll is missing in the libs folder?
