Hi,
If you double click the exe the same rules applies as in the "deployment documentation":http://qt-project.org/doc/qt-4.8/deployment-windows.html

Hi,
I copied dll files (such as: QtNetworkd.dll, QtCore4.dll, QtGui4.dll) which i link library in project into directory same with exe file but also crashed.
-
Did you check each point of the deployment doc ?
Also verify that you have all dependencies with Dependency Walker.

-
Really sorry you, this is my mistake. I use QtNetwork4.dll, not QtNetworkd4.dll
Thanks.

I try to build debug mode in QtCreator and then runing .exe file, result not crashed. But i switch release mode to build, i get crashed when running .exe file.
-
Do you mean it also crashes when started from QtCreator in release mode ?
-
No, I don't.
I'm running in QtCreator in release mode not crash, but runing from .exe file is crashed. Also debug mode, both start from QtCreator and exe file are fine working.
-
Then again, did you check that you have all dependencies/plugins in the exe folder ?
-
OK. thank you for your help.
Let me see again.
