Deployed Qt application finishes immediatly after start

FedorKozlov

I'm developing app in Windows, Desktop Qt 5.11.2 MinGW 5.3.0 32bit
In order to share my application i did following:

Made release build
Copied .exe file to new directory of my package
run windeployqt.exe with --release option

After that, when I'm trying to run my app nothing happend. I assume the app finishes right after start.
It works fine, when I start it from QtCreator, but when I run app manually it seems just stops without any error.

Hi,

Use Dependency Walker or similar to check whether a .dll has been missed (for example the MinGW runtime).

@FedorKozlov
do you use QML in your app ? If yes you'll have to tell the deployment tool where to find the files, to search for and copy the qml dependencies

Make sure your platform plugin is at the expected path plugins/platform/, it's the most likely cause for a Qt app to fail to launch silently.

Thank you! That's the reason
