Yes, the manual updates are basically the same file downloaded by the automatic setup,..... when it works of course. 🙂
Here's few tidbits that I'm fairly sure you're aware of. But heck, I've been in the computer technology business for 35 years, and yet there are times when even I forget "the basics" and pull a Homer Simpson every once in awhile.
For the manual updates, make sure you exit the main program first.
It may help also if you check task manager and if other things like the updater program are still running in the background, you end task on those also.
Run the manual update as administrator, even though the computer account you're using very well may have admin privileges.
If on Win 10, then in the privacy settings check that you have not disabled "Allow apps to access your notifications" along with "allow apps to access your tasks" and also "Allow" automatic file downloads.
