Many helpfull people says YOU DON'T NEED A DRIVE and think that you are skillfull enough to solve the trick... For newbees like me I found A TRICK
This is an undocumented trick: 1. Turn the camera on, and go to the menu. 2. On the 4th menu tab select the "Communications" entry and change it from NORMAL to PTP 3. Plug the camera back into the laptop, wait 30 seconds, and VOILA!
OMG thank you so so so much. I had photographed a football game for my son and couldnt figure out how to do this as I didnt have the Driver software. Got the camera second hand.... this worked.. YOU saved me. you rock. thank you so much.
