Running swf files in local

I would like running swf files in computers without internet conexion.
I don´t know if these computers have flash player, and i can´t download it from macromedia web, obviously.
I don´t know if i can generate a swf file to do that directly, or if i have to have the flash player to install every time in every computer.
Whats is the solution, and how to do it?
