Well I made turning off automatic updating as clear as I can in instructions 4 & 5 of the rollback thread, putting it in bold and adding screenshots of what to do.
I even emphasise it when giving a link, like this:
How to Roll Back from v7 to v6.39
Follow ALL of the instructions, particularly about turning off the Automatic Updating and deleting ‘CCupdate.exe’.
Unfortunately we forum requlars have found over the years that you can put clear instructions of how to do something, but people will still either not read them, think they are not needed (yes they are that’s why we put them there), or simply ignore them.
As the old saying is- you can lead a horse to water but can’t make it drink.
