The smiley 6 is a simple exe application, doesn’t need to replace anything. Just double-click to open it and you will get the window with two buttons, hide and exit. Hide it, and there will be an icon in your tray at the bottom of the screen, when you want to use a smiley, click on that icon and the smiley menu comes up, just pick which one you want to use… make sure the IM window or chat window you want to use it in is on top… that’s it!
