To let other people use a program, it needs to be installed on their computer by that programs installation file. If you got the program on a cd, it will be on that. If you get it free of the web, it will be the file you download. Probably called something like "adobe_install.exe" You can't however simply give a copy of your files to friends and expect it to work. Their computer needs to be set up by the install program first. I would just say to find the install cd or find it on the web. There is no way that I am aware of to copy the program files and get it to work on another comp.
