Precompiled Qt 5.3.1 with dynamic libraries, MinGW 32, Windows 8.1 x64
The deployed application cannot start on another computer giving the error:
Could not find or load the Qt platform plugin "windows"

Solved by copying DLL from Qt's folder to ../MyApp/platforms/qwindows.dll.
Note: there is no "plugins" directory in path
