hello, this camera should not require software, if you plug the camera to your pc it should install automatically and show up in My computer or Computer folder which you can find from start menu or the desktop, it will be named as a "Removable storage device" inside you will probably find DCIM folder and possibly other folders and eventually your pictures, keep looking.
a good software for pictures is picasa.
http://picasa.google.com/picasa can download pictures from your camera, store them on your computer, and you can freely edit them with the program, also it is possible to put the pictures online.
