cannot save word files after 1809 update

Similar issue: Word 2016 with Acrobat Pro 2017.

Acrobat PDFMaker Office COM Add-in is enabled in Word. ACROBAT tab is visible in the ribbon, but all of its options are disabled and Word cannot save any files. 

Once the add-in is disabled, the ACROBAT tab of course goes away and Word works OK.

Moreover, regardless of the Acrobat PDFMaker add-in  status in Word (i.e enabled or disabled), when right clicking on any Word document and selecting convert to pdf, the pdf is not created and I get an error message that Word 2016 cannot open the file as I don't have access to it!!!

I had the same problem with Word.  Couldn't save and then  Couldn't run any add-ins or macros in order to save.

For another reason, my Windows 10 wouldn't boot and I had to perform a "Repair Installing Windows 10".

This essential wipes Windows 10 and all your programs and reinstalls Windows 10.  You can choose to keep directories like Documents (Keep personal files, apps, and Windows settings). 

When I finally reinstalled Word, it ran normally with all add-ins and macros.

This at the moment seems to be the only way to get Word back to normal.

It is amazing the Microsoft does not provide a direct fix!!!!

so how is this fixed?

There's no known fix at the moment - All of us need to start bugging Microsoft support until Microsoft fix it. Currently, you can't run Windows 10 1809 and Word COM add-ins at the same time.

so how is this fixed?

OK simaler problem seams after last update office 2010 will not save in any format
