You can try my fix as described below:
I did these steps and it seems have (temporarily) fixed the saving problem for me:
- Run word as administrator (Shortcut > Compatibility > 'Run as Administrator)
- 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.
- Restart Word
Now when I click on 'Browse' it pops us the window, just as normal.
Oh my God, this actually works! Thank you so much for sharing this with us, you saved me several more hours of pointlessly fiddling with other settings! :D
