Camedia 4.1 disk download

How do I install it from my disk? I get errors saying it can't beinstalled. Is there a free download patch or drivers for it that Idon't have to actually purchase after registration of a computer fixprogram? My disk has a photo program on it that I like and I want todownload it. I can put my memory card into my computer and it willdownload it without installation of the camera but it will not erase mypictures from the card after download. So I guess I have 3 problemsHow do I install it from my disk? I get errors saying it can't beinstalled.
