youll find it hard to find software for hardware you dont know the name of! lol :P did your computer come with a backup DVD? or something similar?
if you put that disk in, dont run it, but open explorer and check the files for something that might appear to be related to a camera. sometimes its blatently obvious, sometimes, you have to search around. it might even be a setup file.
or...last resort! desperate measures and all that! take out the batteries, and look for a label, something very small, in stupidly small print. sometimes, these digi cams do have names hidden in wierd places. mine, is hidden underneath the memory card compartment, without looking, you wouldnt know it!
or of course, you could just go to a random shop and ask soemone, ya never know!
im surprised it doesnt work though...is it usb? this is all i could think of, im guessing you might have solved the problem, this was posted ages ago, but ya never know, it might help someone else one day!
