That's because you're running an interim version that I sent you to fix an issue you were having. I should have said, or maybe I did say at the time, when running an interim version it won't tell you when there's an update and you need to keep an eye out here on the forum and update manually.
I don't recall now what was said, if anything, to be honest. My previous update though was (as again yesterday) installed via the 'manual' exe file I download from this site. Is that an 'interim' version? You mean that if I install from the exe file I will not be informed of updates? I am sure that can't be right - I have not been able to update automatically for a very long time and have had to rely on the exe files for that period. I have definitely had the GUI inform me that an update is available in the not-so-distant past.. (and then, when I run it I get the usual error message at the end, and nothing has been changed).
Whatever, it's not a big problem of course - I can in any case check here for any new updates from time to time.
