after deploy the project?

hi,
i create one windows forms project (c#.net) and i deploy that project and i install that deployed software in my computer it works.
                                     my doubt is i want to install this deployed software in another computer in that computer there is no .Net and no .Net Librarys.
                    if i want to install this software which requirements i have in another computer(Windows XP). compulsary to install .net (or) install .net librarys is enough, if .net librays is enough, this .net librarys are where available means from which website to download this .net librays software.
Thanks.
