IBM computer using Windows 10, range of iPads, one iTouch and an iPod. Updated iTunes to the latest and now iTunes will not recognise the iPads or the iTouch, but the iPod's no problem. Investigation, after following all the millions of words written on this problem, shows me that the AMDS file is not actually downloaded to the computer at all! Six uninstalls and re-installs (following all the exacting procedures to the letter, running CCleaner, rebooting, etc) later, the same situation pertains - the actual file will simply not download. Would welcome any suggestions 'cause I have run out of ideas.
