I recently noted that I was running seriously outdated old versions of MB3 Premium on Win 7 Home, Win 7 Pro, and Win 10 Pro systems. On all these systems, I had configured the Settings>Applications Update>Automatically download and install radio button to "Off". I had the "Notify me when full versions are available" radio button  set to "ON". Despite these settings, I was not notified of any new versions of MB3 Premium for almost one year on all these systems. I had to use the Settings>Applications Update>Install Application Updates [button] to initiate a search/download/install of the latest MB3 version.

Most users of MB3, I suspect, already choose the "automatically download and install" option for new versions. I post this info for those who, like me, want to review new software prior to installing it. It appears that MB3 Premium  is not currently notifying me when new versions are available.

As always, YMMV.
