I cannot uninstall or upgrade icloud 3.1
I am trying to update icloud from 3.1. to 4 on a Windows 8.1 pc.
It won't install from the Apple Software Update console, nor from the downloaded updates folder: I get an error 'The specified account already exists', it then rolls back.
I've tried signing out of icloud and uninstalling, but get the same error 'The specified account already exists', it then rolls back.
I've tried renaming the Apple folder in c:/program files (x86)/common files to 'Apple.bak', but get the same error.
Grateful for help please so I can update it to version 4.
Thanks!
