QtQuick Application crashes (at runtime) after deployment on windows

[themts]

Hey guys,

I'm trying to deploy my application on a windows machine.
I copied all necessary files to a folder (btw. I think there should be a automatic function for this in qtCreator, as qtCreator should exactly know which plugins and files I'm using) until I was finally able to start my application without any exceptions.

Unfortunately it's quite simple to crash the application:
I'm using 2 components from QtQuick.Controls:
a) Menubar
b) Combobox

Both components are visible after application start. I can even open the menubar as well as the combobox but as soon as I close one of them the application crashes.
I have no idea how to solve this problem as its working when I start it from qtCreator.

Any idea?
thanks!
mts

EDIT:
For testing purposes I placed a few other QtQuick.Controls on my mainForm without any problems. It seems only to crash on components which show a menu

I just uploaded a simple testApp:
testApp on uploaded.to

It's a package with all my included dll's I have collected from the qt folder

Maybe I should post some more details:

Compiler-Kit: MSVC2013 openGL 32bit

Application crashes:

• when I open a combobox
• when I close a menu from the menuBar
• when I close the application

Unfortunately I don't know how I should debug it, as it's not happening when I run it from qtCreator.

Hi,

You can have a look at the windeployqt tool in your Qt installation folder. It is not perfect yet, but it tries to automatically deploy your app.

I have no idea how to solve this problem as its working when I start it from qtCreator.

Clear your deployment folder, and then follow every step under "Initial Deployment (Quick and Dirty)" at http://wiki.qt.io/Deploy_an_Application_on_Windows closely. Does it still crash?

sorry, my mistake...
I found the problem! I mixed up dlls.

I don't know why, but I used some dlls from:
QTDIR\5.4\msvc2013_opengl\plugins
and some from
QTDIR\Tools\QtCreator\bin

Yeah... don't do that ;-)
