I want to ask , how I can got MS Project by free, without insllating Microsoft office 2007 components( ms word, exel, powerpoint... etc), not: I don't have ms office 2007 CD :D

Simple YOU CAN'T.

MS Project is commercial software so to get it for free, someone would have to give it to you as a gift or you steal it. And we don't condone stealing.

You don't, however, need office to install Project.
