My OS is Vista. I have updated my Zoom Browser software. I was not able to download pictures from my Powershot A40.

Try NOT connecting your camera to your computer.

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 cataloging program.

thats also known as a powershot a40 - heres the support site for that camera http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&fcategoryid=221&modelid=8288 if you goto the drivers and download tab - here you will find a manual - for zoom browser and the camera You should be able to connect the camera to your computer with a supplied USB cable - and then the zoombrowser software should detect your camera connected and offer to transfer images In the manual on Page 126/128 explains how to connect camera to PC Also explains in the manual how to transfer the images. If your PC has a memory card reader you can transfer that way - also explained in the manual

Canon did not update drivers under the Vista OS for many of its cameras, the A40 included. Please see the following blog article, as it describes the use of a card reader as a much easier, faster, and less error prone way to download your photos. In fact there are several important reasons discussed in the article for using a card reader vice downloading from the camera. USB Card readers are also very inexpensive these day, with cost virtually not an issue:

It's very hard to troubleshoot software problems online, and it likely is a software issue. But why put up with the headaches of bad software in the first place?

Go to Canon Support and Select OS (Windows etc) and download required zoom browser software. Install it and have fun with A560.

I had same problem. Called Canon and found out A40 is not compatible with Vista so there is no driver. But you can download pics to your Vista by purchasing USB Memory Card Reader/Writer you can find at Walmart for about $12.00. You put your Flash card in device and has USB that plugs in computer for downloading pics.

You may go to the link below then select Vista from the OS list

I hope this has answered your question sufficiently. If you have more questions please post a reply and i would be happy to assist. Thanks

Ouch. The ONLY "official" solution I could find was this: "If you have lost youroriginal Solution Disk, you can purchase a replacement by calling Canon Photo/Video Spare Parts."

OTOH, I did find this file:

== Be careful downloading files. Scan it with virus-scan before opening and installing. ==

BTW, updaters for some versions of the Zoom Browser can be found at: usa.canon.com.

You do not need any sort ZOOM BROWSER. Try Picasa from Google. It is free and works way better than any OEM proprietal browser.

If you have a Vista, it is not compatible. It will not download the Zoom browser. I had to purchase a Memory card reader/writer to download pics on my laptop from my camera and by passing the printer.
