I have a bunch of computers with windows 7 or 10. The 64-bit computers all update correctly. The 32-bit computers fail to update with some nonsense about a file having been "updated by other means", even when the file doesn't exist.

It's been a slow process. Firstly the windows 10 computers failed, then slowly over the next months and years, the windows 7 computers failed one by one, so now there's only one left on the current release.

So, while the installed version does what I want, it would be good if it was the latest version, without having to reinstall the whole thing.

My questions are
- Has anyone else struck this problem?
- Is there something that can be done to make the updater more reliable?

I don't want to know about alternative readers, switching to linux, or any other OT things.
