Answer 2

Check if the icon (favicon.ico) in the same folder as the executable.

Answer 3

yes its in the same folder

Answer 4

Well, I assume that you forgot to provide the icon together with the executable. But in any case, it would be better to embed the icon as resource in the executable. Have a look at the Qt resource documentation. Basically, you just need to create a resource file, add the icon and then change the filename to something like this ":/favicon.ico". By adding the ":/" in front of the filename, Qt knows to load this from the embedded resources.
