When I try to download pictures from my Canon A520 camera to my computer, I get a message saying the computer can't detect my camera. The software is loaded. The camera is in play mode. In the past I was always able to do this.

Are you using the canon software to download the images and downloading the images through the camera not a disk reader. Sometimes the computer will recognise your camera as a HDD when using the canon software by connecting your camera to the computer with a USB lead. Worth a try.

When did it start?

Did you try re-installing the camera's software?

Do what the pros do...use a card reader instead of the camera.

install the software with the camera and cable unplugged and then try again

Try uninstalling your digital camera software, restart your computer, then reinstall the software. This should reboot your camera and it's components.
hope it helps!

I have Olympus Sylus 1030 SW and I have the same problem, my msn messenger cannot detect camera. How do I fix this problem ?

Download the software and then install it once that is done connect the camera to the usb port on the computer it should automatically detect the camera once it is turned on.

software canon

Same problem here.

Very Annoying!!

when downloading from my EOS 350D I get the message
'Camera launcher exe has stopped working'
I have Vista Home Edition
I am getting desperate to find a solution!!

ya. picassa wont do any help to you brother. you may have connected the camera and switched it ON right?
after switching it ON change it to play back mode( mode in whih you see your photos) that time only camera detects the computer.

even if this is not working try a different cable to connect it.

else use your friends system to check if camera is really faulty.

even if its not working take it to service center. dont forget to take your warranty card and purchase bill there.
