Why my app Icon is not used?

[qwe3]

Hi,

I have strange problem.

When I compile my code I have my custom .exe icon. In .pro I have:

RC_ICONS = resources/myCustomIcon.ico

And it works.

But when I add to my .pro lines ( there are before RC_ICONS ):

win32 {
    RC_FILE = myRcFile.rc
}

My compiled .exe has default windows icon:

How can I changed that?

EDIT:
Look this :)
