Answer 1

Your problem is probably because Windows can't find the Qt libraries. Try placing the required Qt libraries (for instance QtNetwork4.dll, etc...) in the same directory as your .exe and see if it works.

Answer 2

You can use Dependency Walker to help you find out what Qt DLLs are needed and copy them to the same folder as the .exe.
