I want to know if any of you guys have ever copied programs from another computer

.........i mean i already tried to get some programs like Photo Shop and Illustrator but it seems that i didn't copied all the necessary files and data so it could be installed in my computer and run correctly

. I open...C:\Program Files\adobe\Photoshop cs...and i copied everything in there...however it could not be installed in my computer........i don't know what else would be necessary......Photoshop, illustrator, and this program i found to be like illustrator called CorelDraw (version 11) is what im trying to get

...........I hope some one knows what is necessary to make this kind job........thanks for any help you guys can give me
