i found QtCore.dll / QrCored.dll but there is not QtCored'4'.dll
some other program have QtCored4.dll
what is '4' ?

The number '4' - is major version of the library.
Major version, if you are going to a shared library.
You have to get the files: bin/Qt{Module}4.dll and lib/Qt{Module}4.lib
If you have collected Qt statically, the major version is not affixed.
You should only get lib/Qt{Module}.lib files.
