How to change app ICON´s?

hi there guys, long time since i’ve started a tread!

well, i’ve just programmed a cdrom application, and created macOS (.icns) and windows (.ico) icons.

i’ve already figured out how to change the flash icon to my own in macOS, but i can’t change it in [COLOR=“Red”]windows vista[/COLOR]! i remember that it was possible to change the icons in previews versions of windows. tried to find information at google, but nothing came up…

can anyone help me out? :beer:

thanks in advance!
