I created a small .ico for my program. Now I want Qt to set it as the applications icon. 

I found this documentation but it doesn't seem to work : <http://qt-project.org/doc/qt-4.8/appicon.html>

I did exactly what they want me to do. 

1. Create an myapp.rc file and write `IDI_ICON102 ICON DISCARDABLE "Movie-World.ico"` 
into it. -> Did that.
2. Write `RC_FILE += myapp.rc` into your .pro file.  

-> Did that.

When I compile and run, it doesn't work. I deleted the realese folder but still no changes. I restarted Qt but still no changes.

I even added `win32:` before `RC_FILE += myapp.rc` but it did not work...

I don't understand why. My files are all in the same directory.

Now I get this error message :
