Install Apple iTunes on Windows 7 QUESTION My three-month-old Acer Aspire Z5610 all-in-one PC runs Microsoft Windows 7. I recently tried to install Apple iTunes, but AppleMobileDevice refuses to play ball. Acer blames Apple; Apple blames Acer. With my brand-new PC unable to run such a common application, I'm seriously considering returning it under the Sale of Goods Act. David Jackson HELPROOM ANSWER The onus here is on Apple, not Acer, David. It's Apple's software that's failing to install, and Acer has no liability for fixing other company's problems. That said - and I have few details to go on - I suspect the problem may have arisen from you upgrading from one version of Windows 7 to another. The following tips may help you find a fix. Uninstall iTunes and any Apple software currently installed on your system. Reboot. Delete any Apple folders in Program Files. Check in the Program Files (x86) folder too if you are running Windows 7 64bit. Download and install CCleaner. Run both the file and Registry cleaning applications. Reboot the PC again. Next, head to apple.com/itunes and download the correct version of iTunes - you'll find separate downloads for x64 and x86 systems.
