QT windoes deployment Problem. DLL

[Keltner]

Current Environment:

Build information : Qt Creator 2.7.0 Based on Qt 5.0.2 (32 bit) with both MinGW as the compiler. XP PRo Box

Original Environment:

Original Source was made on qt creator 2.6.2 qt 5.0.1 (32 bit) MinGw on a mac with windows seven.

Information on What I am Trying to do:

This Project is being used with a application called Metatrader 4 and is used to enhance the GUI of Metrader. With in Metatrader I can launch the qt app with shell execute A... some times it works some times it does not. So I have converted the QT project to a DLL.

Information on Problem:

It executes, complies and runs fine on the Boxes with QT deployed and installed. On any other Boxes I get a Error 126.

What I have tried: **

Dependency walker gives me this error API-MS-WIN-CORE-HANDLE-L1-1-0.DLL . This current box I am working on has XPRO.

The Question I would like to ask?

Why the error 126 when the exe works perfect? any thoughts?
