Larger App Icons for Windows

Hi there,

is there any possibility to change the app icons larger than 256x256px? If I build an .exe File, it shows me the red lightning icon if my folder settings are set to "Large Icons" or higher. In the properties I've only found an option to change the Icons for 256x256 or smaller.

Thanks for your answers :)

Windows uses an icon cache and doesn't refresh it everytime. If you change the 256x256 icon in the properties of the application and still see the original icon in a Windows explorer, close and reopen the explorer, or even restart Windows. I think there are "methods" to erase the Windows icon cache but I don't remember very well.
