I have developed a simple application with Qt 5.0.2 on Windows 7 Ultimate. As a compiler the QtCreator used MSVC2012_64bit. And I cannot move my application onto other computer. It does not work. Qt application requires DLLs that I can't find. The dependency explorer thinks that the .dlls below are not found. Where I can find them? Why is this problem so wide spreaded? All the people complain that they can not get their .exe, which is developed with Qt, work on other computer . enter image description here

EDIT1: BTW when I have added DCOMP.dll downloaded from the internet, the not found dlls become 2-3 times more than it is now :)

EDIT2: Also note that on other computer (Windows 7 Home Premium) when I double click on the exe file, it shows that it loades and no effect, no error nothing at all.

This the list of dlls I needed and also I have copied the C:\Qt\Qt5.0.2\5.0.2\mingw47_32\plugins\platforms folder:

Just this and it worked for me. BTW I use Windows 7 Ultimate 64x, and Qt 5.0.2 for Windows 32-bit (MinGW 4.7, 650 MB) package for Qt.

EDIT: You might also need QtCreator's .dll to be copied and also you might need to have a file named qt.conf with the following content (copied from @Renato answer):

Libraries=./platforms
