How to run a Qt program without installing Qt?

Question

I wrote a program with Qt5.3.1 and ran it on my development machine, where it works fine. I copied all the necessary .dll files to the folder where my .exe is located. It:

• Qt5Widgets.dll
• Qt5Network.dll
• Qt5Gui.dll
• Qt5Core.dll
• icudt51.dll
• icuin51.dll
• icuuc51.dll
• libgcc_s_dw2-1.dll
• libwinpthread-1.dll
• libstdc ++ - 6.dll

Now I want to run this program on a machine that does not have Qt. How should I do it? Users will not need to install an IDE just to use the program, right?

Details of the development machine, where it works:

• Windows 8
• Qt 5.3.1

Deployment Platform:

• Windows Vista li>
• No Qt, but all the necessary .dlls are in place.

The errors I get are the first:

, Qt "windows". .

:

, Runtime . .

. , Qt5.3.1, . c:/Qt
