Assuming now that you are OK on the DLLs, and the deployment went well/didn't report anything, nobody will be able to tell you why your app may be behaving like this on a different installation. There are many possibilities. You either have to debug (may or may not be convenient), or you have to a insert a few "print"/"logging" statements or similar into your code to get an idea how far (if at all) it gets through the start up/code.
@Zunneh, I notice that you tried to launch a Debug build. I can tell because all your DLLs end with a
Have you tried deploying a Release build? (Your app should be deployed with Qt5Core.dll, Qt5Gui.dll, ... not Qt5Cored.dll, Qt5Guid.dll, ...)
