I have a Canon EOS Rebel XTi camera, the solution disk I have is version 13.1, which worked well with Window XP, I now have Windows 8.1. The disk of course will not work. I can't seem to find anythin

Having same issue as above - I thought it was my cable so I ordered a new one. The camera attempts to 'speak' to the pc - and then the Windows box pops up not recognising the USB installed device....I also uninstalled and reloaded the Canon software (had camera for 18 months and only started this rubbish a month back) - was about to re-laod my entire PC - thankfully I saw it was not only me.

Will send mine in for a Firmware update / service.

I believe there are 2 modes of usb transfer that you can pick in the camera. They are set somewhere in the menu in the options. If you go through the menus thoroughly you'll find it. One option is for connecting the camera directly to a printer and the other is for computer transfer (there might also be an Auto setting but I don't remember for sure). Make sure that setting is set for computer transfer. If that doesn't fix your problem, re-install or update EOS Utility / ZoomBrowser.

I contacted Canon technical services through email. Then we uninstalled everything and reinstalled an it worked!

Vista is your problem. Solution...buy an inexpensive card reader to download your pics to a folder you create on your desktop. From there, you can send the pics to your photo editing software.
