you can google search for installer. I think this is the one i have used
http://www.clickteam.com/English/install_creator.htm. if this is the one then it compresses all the data you tell it to install into one installation programme therefore they cannot use any parts until it is installed if that what you mean. you can also choose to create a shortcut in the start menu and desctop through the installer packages.
Im sure there is laods of free icon creating pieces of software out there i made one with a very basic one that come as part of liberty basic ([href]www.libertybasic.com[/href]). Then to add the icon to the shortvut right click on the shortcut and go to properties and it can be changed in their. Also i think you can select the icon used with the installer package i showed u, as long as that is the 1 i used :S
hope that helps
