This, though, was only the 3.2.2. 1300 version and so (as expected) I received a notification that an update was available and I downloaded it.
Unfortunately when I ran the set up file I received the error message shown in the screenshot below.

I tried "retry" (as suggested) 4 times without success and then aborted.
Can anyone please recommend what I should do to get round the problem?
I think that by uninstalling my current version and then re-running the update setup that would solve the issue but I'm hoping to avoid having to do that if at all possible.
Thanks in advance.
