How to deploy to Windows Embedded Standard 7?

[martini]

I read that WES7 is basically win 7 "here":http://blog.qt.digia.com/blog/2011/10/04/qt-commercial-on-windows-embedded-7-2/ . But my app crashes on the target "device":http://www.aaeon.com/en/p/3-and-half-inch-sbc-gene-9455-rev-b/

I compile using mingw on 32 bit win7. The target device has a 32 bit windows 7 embedded standard installed.

The error says nothing. Only that Qt5Quick.dll crashed.

The folder structure is:
icudt51.dll
icuin51.dll
icuuc51.dll
libgcc_s_dw2-1.dll
libgcc_s_sjlj-1.dll
libstdc++-6.dll
libwinpthread-1.dll
Qt5Core.dll
Qt5Gui.dll
Qt5Network.dll
Qt5Qml.dll
Qt5Quick.dll
Qt5Svg.dll
Qt5Widgets.dll
folder platforms:
qminimal.dll
qoffscreen.dll
qwindows.dll
folder plugins/imageformats:
qgif.dll
qico.dll
qjpeg.dll
qmng.dll
qsvg.dll
qtga.dll
qtiff.dll
qwbmp.dll
folder qml:
main.qml
folder QtQuick/Controls:
...copied from install dir
folder QtQuick/Window.2:
...copied from install dir
folder QtQuick.2:
...copied from install dir

The main.qml file is:
@import QtQuick 2.0

Rectangle {
id: root
width: 800
height: 600
color: "#313131"
Rectangle {
color: "red"
x: 50
y: 50
width: 100
height: 100
}
}
@

If i get rid of the whole qml folder, then the application runs but there is only a blank square window.

Any suggestions?

Do I need an embedded version of Qt for a WES7 ??
