[omid_kma]

Hi
I release prject with Qt 5.1.0 for windows using Windows 32-bit (VS 2012, 511 MB) then I put necessary dll s Including plugin folder ( with this application
And then I run application in my own pc every thing works fine but when I tried other pc that doesn't contain Qt it doesn't start (no error just doesn't show any thing !...)
Things that I have done :
I installed visual c++ 2012-210-2008 Redistrutable packages
Putting all dll s even debug ones !
Putting plugins folder

I tried dependency walker but it seems nothing is missing !!

Note that I have same probem with mingw version of Qt 5.1 too !
I tried using this qApp->setLibraryPath(dir);
Thenit runs but still cant play sound (doesn't recognize multimedia dll this one I think dsengine.dll !!)
I use QMediaPlayer and QSqlite in my application and I added all necessary dll s

Any help?

Did you create a folder called platforms inside your application directory and add qwindows.dll into that folder?

Yes I do see the picture I attached...

copy all of contents of plugins folder into your app to see if works. Did you used qml module in your app? Did you used third party libs in your app?

If you used qml, then you have to copy contents of qml folder into your app folder.

As I said,I tried it before.

No . I didn't use qml too.

You said that the sound is not playing and the app has launched. so the problem is not triggered by dll and i think it has to be the path. are u sure about path of your sound files? ( have u added it into your resources or gave it an absolute path?)

I signed up just to thank you. You saved me. Qt can be such a nightmare! I spent hours trying to figure out why my app would launch but no GUI popped up. That was it. I use the windeployqt tool and it doesn't import the qml folder for you. Ugh what a horrid nightmare. Missed my project deadline because of it.
Thank you.
