QProcess : "Unknown error" when exitCode() != 0

I whant to deploying this project before the end of my job (Friday).
I understant i must run with "release" and not "debug".
I understant i must add my dll at "Select Projects, Run Settings, expand the Run Environment".

But outside Qt Creator it's like my dlls arn't add :

At the end i want deployed my application in static (i thinks it's better no ?)
I whant it woks on windows and linux and the image on button it's visible (i use qrc ressources before it's works (again ^^) and know no).

hi
Please STOP a moment
you are mixing stuff up, or i really do not understand what you are doing :)

1: running in creator.
You need to add any dlls that is not part of the Qt so when Creator runs the app, it can find those extra dlls.
That is the "expand the Run Environment" part. ( to PATH )
There should be no need to add any Qt dlls for that.
Setting ANYTHING here have no effect on deployment what so ever.

2: Deployment
Running the app on another computer with no Qt installed.
For that you need the deploy folder with the right subfolders and
all extra Dlls and the Qt ones you need.
There is a tool call windeployqt
http://doc.qt.io/qt-5/windows-deployment.html
that can help copy the right QT dlls to the folder.

This deployment folder, you then give to others and they can run the application.
For more info about the deployment folder, i like this site alot

And AGAIN, deployment and running in Creator is 2 VERY different things.
