"failed to initialize" camerawindow-downloading images to macbook

Shutter is Faulty and needs to be Replaced.

If it is on the LCD only and not on the final image when downloaded, it could simply be the camera indicating the actual image area that will be recorded. This can be changed by selecting a different aspect ratio.

You can always use a card reader to download your pics.

The shutter flex cable inside the lens is broken. Happens to all cameras from Canon A4xx series. At day the images will be overexposed with horizontal lines on it, but it could look better at dark / night. The FLEX has to be replaced. Canon doesn't supply new flex cables for these, but there are some cheap copies on ebay. But as these brake very often, I wouldn't suggest you investing money in this camera, because it will brake again sooner or later.

Solve your problem by using a card reader to download your pics to a folder you create on your desktop.

Go to this website http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=DownloadDetailTabAct&fcategoryid=320&modelid=16338 select your operating system and then download and install driver, that should work. Guy

You can use microsoft scanner and camera wizard to download in the meantime. I'm not sure what is going on with your Zoombrowser software. Which Operating System are you running?

If your computer has a SD card reader, you might be better off putting your memory card into your computer and just copying the data.

Have you made sure your iPhoto is up to date? Perhaps a new update caused this problem.. Maybe you should try an older version of the software. Also, you might want to try other software. (I think you are on a mac?), you might want to try the software that came with the camera, if it works on your computer.
