cannot save word files after 1809 update

I have exact the same issue.

It is the COM Add-in "Microsoft Office Remote Support for Word" that causes this issue. Disable it and it works again. Although considered a work-around.

Hi, thanks for giving a solution, however in my case it does not work because I do not have any COM complements, I already try blocking Microsoft complements and the problem persists. I hope another solution can be delivered soon.

It could be. In my case, it's not only the acrobat add-in, but also the additional add-ins from Microsoft, OneNote ect. I have tested it, one by one and I have to disable all Add-ins to make it work.

You can try my fix as described below:

I did these steps and it seems have (temporarily) fixed the saving problem for me:

1. Run word as administrator (Shortcut > Compatibility > 'Run as Administrator)
2. Start Word and then go to File > Options > Add-ins,

* Under manage tab ''Manage: COM Add-ins'' GO

* Deselect all add-ins and then type Ok.

3. Restart Word

Now when I click on 'Browse' it pops us the window, just as normal.

Thanks for the tip, that worked for me.  In my case it was the Adobe Acrobat add-in, maybe that's related to the root cause?

You are welcome. Glad to help!
