Again, thanks for explaining however, I am still having a problem understanding. Could you possibly post a picture of where the Addon Manager ask "updated notifications"
As soon after you launched any FSDT installer, the Addon Manager got its latest files, which includes data about all the product. If a scenery needed to be updated AND the old version is found in your system, you'll see a warning like "your xxxx scenery is outdated, please download the current version". You'll also be asked if you want further notifications for that scenery so, if you reply No, that message will not come anymore for that specific scenery.
I do not remember ever seeing this.
It simply means you were careful to keep your sceneries updated, without waiting for the Addon Manager to notify you.
Also, If I am understanding you at all, when I just recently purchased and installed PHNL, KLAS, and KFLL, I would automatically be informed if my KJFK, KORD, KDFW, KLAX and ZurichX contained any outdated files?
The act of purchasing doesn't really matter. What triggers the possible update notification is launching an installer, even an old one. It doesn't make any difference which installer you are launching, since they all get the same Addon Manager files.
What's make the difference in getting the notification or not, is if you are launching an installer after the date a scenery you have installed is updated AND we setup an "old scenery" notification for it, because we decided that update was significant enough to alert users about it.
As I've said, it's the next best possible solution rather than having something resident in Windows or something that access the internet at each Flight sim start. We would have more precise update notifications in that case, but some users might be scared of the Addon Manager "calling home" in some way...
