The strange thing about Microsoft Word is that if you try to open a '.asd' file that is not in the Recovery Folder
(usually '%appdata%\Microsoft\Word')
then it will refuse to recognize it altogether!
But if you put the very same file in the Recovery Folder
(or even in a subdirectory of the Recovery Folder),
then Word will open it without so much as a whisper of complaint!
So just open an Explorer window,
paste '%appdata%\Microsoft\Word'
(without the quotes)
in the Address Bar and hit 'Enter'

Copy and paste your '*.asd' file into the open folder and click on the file to open it.
It will ask you:
'How do you wish to open this type of file (.asd)?'
'Look for an App in the Store'
'More Options'

Choose 'More Options'
Tick the box []'Use this application for all .asd files'
and scroll all the way down to 'Word (desktop)'

and click on it.
Home and dry!
