You don't need a driver.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo management program such as Picasa ( http://picasa.google.com ).

The C1450 records audio but will not play it back. To hear your videos you must transfer them to a computer and play them there or connect your camera to a TV. See the bottom of this page of the extended user guide.

Hello, Kodak has no control over your cameras' ability to upload your photos to your PC ! Unless you are talking about their online photo storage. If you are having problems transferring your pics to your PC and are using Kodak software try to reinstall the program and see if that works, I don't think your camera is junk.

Try the steps in this tip.

You need to remove the batteries and remove the memory card. Then reinstall the batteries. Finally, press and hold the "ok" button, the power on the camera. This is a factory reset trick. It fixes approximately 40% of all error messages on the KODAK EASY SHARE CAMERAS. But of course, no one is gonna be kind enough to help somebody out, they just want to take your money!

The C182 records audio but does not play it back. To hear the audio, first transfer your videos to your computer and play them there.

Try downloading the clip to your PC. Some cameras record the sound but don't have a speaker to play it back.
