What files are needed for a release build with Qt Creator?

Question

I compiled the standard qt widget project (Desktop Qt 5.4.0 MSVC2013 32 bit) as a release build with QtCreator 3.3.0 on Windows 7 32 bit and put the qt libraries in the same folder (Qt5Core.dll, Qt5Gui.dll, icudt53,dll, icuin53.dll, icuuc53.dll) And when I start the program the error (roughly translated) "... doesn't work anymore" appears.

When I do the same thing with the debug release and put the appropriate debug libaries in the folder it works.

What do I have to make differently with the release build?

Thanks in advance for any help!

Try to deploy your application using The Windows Deployment Tool which could be found in QTDIR/bin/windeployqt.exe. It automatically puts all necessary files in your application directory.

Open your command prompt and add the path to your Qt directory and it's bin folder to the PATH variable like :

set PATH= path\to\Qt\bin

Next run the windows deployment tool with your application path as the argument:

windeployqt.exe  <path-to-app-binary>

This way you make sure that the deployed application would work on any computer and you have included whatever necessary.
