The procedure entry point could not be located in dynamic link library

Question

I have the following error when open my application.

I'm use windows 7 32bit platform, and Qt v5.3.1 with MinGW 4.8.2 - 32bit compiler .
All dll's files with Qt5Core.dll for 5.3.1 version already exists .
I don't know how to solve this problem.

Solution

Probably you get this error because you use dlls from QtCreator directory which was not compiled with mingw (often QtCreator compiled with Microsoft visual studio on Windows)

You should use dlls from C:\Qt\Qt5.0.1\5.0.1\mingw47_32\bin (for example) .

App which was compiled with mingw needs dll which compiled with mingw too.
