W10 various versions, 'registered iFilter is not found' in index

[vv80894537]

The past 2 months I've been having problems again with searching PDF content in attachments on Outlook.
These problems have come and gone in the past year, I managed to fix them at the time but alas, it's broken again.

This is how the indexing looks like on Windows;

In control panel --> software you clearly see the adobe ifilter (newest version) installed but it's never recognized in the indexing menu. It just doesn't work. I've tried reinstalling it and reinstalling Adobe, I've tried a different W10 PC, etc....

Anyone know a fix for this?
It's similar to this problem

Install the latest iFilter and this;

PDF search breaks after 11.0 install of Adobe Acrobat or Reader

And it's fixed!ç

I've had 2 more complaints past week that it's not working anymore with Windows 10 1809 . I'm not 100% sure if it's actually broken , does anyone perhaps have some more info?
