Say I wanted to copy a program onto a CD to give to someone else so that they could install it, well I'm wondering how it would work.

Is it just a matter of me copying the entire program folder onto the CD? Because I know when you install a program from a CD there is usually a setup.exe file which you start with, and this installs the program for you. But in the folders of my programs now, on my computer, there is no setup.exe file. So if I just copied the folder to a CD, would the person on the other end be able to install the program?

Or can it not be done without copying from the original CD that the program was on?
