Windows QT Deployment not working (VS2010 + QT 5.4.0)

[yafes]

I have:
Windows 7 64bit
Visual Studio 2010
QT 5.4.0_MSVC2010OpenGL_32bit (opengl)

When I run the release from QT-Creator, it’s successfully starting the Application. When deploying using windeployqt.exe it’s not working on any other machine, which has not installed QT.

Tested Solutions not working or partially:

1) Using windeployqt.exe

As suggested from Forum threads, I used windeployqt.exe for deploying, the commands I’ve used

a) First setting the environment variable for my QT version
@set PATH=C:\Qt\5.4\msvc2010_opengl\bin;%PATH%@

b) Calling windeployqt.exe with path to my executable
@windeployqt.exe C:\build-AssetBrowserWidget-Desktop_Qt_5_4_0_MSVC2010_OpenGL_32bit-Debug\debug\AssetBrowserWidget.exe@

Output of windeployqt.exe:
@Warning: Cannot find Visual Studio redistributable in C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\redist@

But I files are persistent in:
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\redist\x64\Microsoft.VC100.CRT
a) msvcp100.dll, msvcr100.dll

Anyhow this shouldn’t be the problem why the Application is not starting. (Go to Point 4 for the Reason)

2) I tried the naively copying copying all .dll files (those in Qt) into the root directory of my application
C:\Qt\5.4\msvc2010_opengl\bin
C:\Qt\5.4\msvc2010_opengl\plugins

I tried as well to copy the insides of plugins all *.dll to the root

This didn’t change anything

3) I tried to setting the library Path in my Code before the QApplication is started and this worked partially

a)
@ b<<".";
QApplication::setLibraryPaths(b);@

This starts the Application, but obviously the plugins are not fully loaded, as the SQLite module isn’t working. The folders* sqldrivers, imageformats, iconengines,* are not touched, as i can remove them and nothing changes. The qwindow.dll which is under “paltforms” is seen by the application, when i remove the folder platforms, the application is starting and crashing immediately like before.

b)
I tried to set the Path to the plugin
@QApplication::addLibraryPath( QApplication::applicationDirPath() + QDir::separator() + "plugins");@

4) Hiding System Files on developement machine
One more thing to mention, when i "hide" the* C:\Qt\5.4\msvc2010_opengl* folder then my application isn't starting on my development machine either, so i am sure, some files in this directory are missing.

I am completely lost and i am really asking, why every other bit in Qt is smooth but the deployment process is obviously not out of the box.__

Here i am posting as well my Pro file:

Hi, agreed deployment of Qt apps can be troublesome, I think you need a complete list of the DLLs used by your app:
Start your app from Qt Creator, then try this utility: "ListDLLs":http://technet.microsoft.com/en-us/sysinternals/bb896656.aspx

Launch ListDLLs from a CMD window, e.g. "listdlls AssetBrowserWidget", then you'll see where the plugins are loaded from.

Hi and welcome to devnet,

Do you have any error message ?

Note that you are trying to deploy a debug build, you should first make it a release

[yafes]

@hskoglund i will give that a try tomorrow
@SGaist the error message is somehow gone, i had it as an image, but it was something like "runtime error" without much informaiton. Furthermore i tested it both with Release and Debug.
