...where can ich free download software to

You will need to replace the camera, it is not cost effective to repair it

Hi,

Here is a tip that I wrote about how to find the manuals, drivers, downloads andsupport for Digital Cameras.

DigitalCamera Manuals, Drivers, Downloads, and Support

The quickest way to do that is to attach the camera with a USB to the computer directly without any card inserted. Then click Start/My Computer and your internal memory folder should appear as an external memory along with C: D: etc.
There may be also a similar way using the software provided by Canon when you bought the camera?. Hope this works.

I've search the driver via google, but I couldn't find proper solution for you. Maybe you can try to visit (or maybe you already visited) this sites :

Hope this help. (^_^)

there is only problem with your battery please replaced with good one it will work fine.

Your problem may be due to corrosion on the battery contacts inside the camera which can prevent the full power of the batteries from flowing into the camera. Try this free fix before you do anything else: remove the batteries and wipe the camera contacts firmly with a dry cloth (heavy corrosion may require cleaning with a wire brush, steel wool, or sandpaper). Remove any residue that may have fallen into the battery compartment during cleaning, then wipe both ends of the batteries and place them back in the camera. This cleaning clears the problem about 90% of the time. If it doesn't work for you, the camera may have a problem that requires professional repair.

If this response helps, please post a rating for me. A rating of "Very Helpful" would be appreciated . .

go to download driver in googles and type in name of camera for vista and download it and then install it

Use a card reader to download your pics.

More then likely you have a speck of something on the inside of the lens.I would contact the company directly. Here is there contact info:

Hope this helps.

From Pentax. There is nothing in the software that you need to operate your camera. The software only provides imaging programs that you can use to change your images. Download a program from Google like Picasso, it's free and as a rule better software.
