I have a simple question, mostly out of curiosity. When I build a release version of my program using a Setup project in my solution, VS 2008 creates two installation programs. One is titled setup, and the other is the name of my program + setup. The second is also called a window installation package. They both install my program fine. My question is simply what is the difference, and when I distribute my program, which one should I use, or does it matter? I am inclined to use the one with the program name since it has a more descriptive title.
