Mingw 64 in Qt 4.7 [windows]

[reed987]

Hi,

I would like to ask how to create a 64 bit application under windows in QT 4.7 with mingw64. There are some topics about this issue but they are too difficult for me :(. Can someone explain me in a very simple manner how to do this?

I know that the first step is to download the 64 bit version from
http://mingw-w64.sourceforge.net/download.php
But what next ?
