Updater always has all actions ticked and so won't allow an update?

NC12 and trying to update to NC12.01.

I get the notification of an upgrade and select ‘open updater’.

This take me to the updater, but instead of waiting for the download it has all the actions of an update ticked, as though it has finished?

It has happened a number of times and always means I have to update manually.

I am asking as so many people have exclaimed success in the web updater, I wanted to understand what was going wrong with mine.


Thanks in advance.
