If it is older software, it is probably not made to run on Vista Operating Systems. I would check the market for something Vista compatible. Samsung might even have updated software on their website for purchase. But you might want to do some bargain hunting around the net first.
Or you could always just connect the camera to the computer and copy the pictures into the "My pictures" folder on your computer. And with Vista's "Windows Image Viewer" (or something of that nature) you can do basic things to the photos, like adjust brightness, contrast, or saturation. You could also crop the photos, and more. The Vista provided image viewer is probably equal to what you could do to photos in the software.
