I've tried to download the Windows 8.1 upgrade 4 times. The first time it told me to login as Admin, which I did, but this made no difference. I keep getting the very unhelpful message: "Your Windows 8.1 installation couldn't be completed. Something happened and the installation of Windows 8.1 can't be completed. Try Again."
I have Windows 8 Pro since November 2012 with automatic updates turned on always.
Any suggestions please
