Hi,
i changed in the project settings the icon of the project and then packaged a 64bit shipping release of my project, the icon i use is a 512x512 sized icon file.
I can see the changed icon on my exe.
I also changed the editor splash and the game splash (btw. if you change the editor splash, you cannot overrwrite the custom splash, you need to delete first your custom file).
If i now launch the game by using the exe, the windows title bar shows the unreal icon (But the correct project title), in the taskbar it is also showing the unreal icon.
This is reproduceable in every project.
Thank you for your help
