Perhaps an easier &/or better idea may be to get and use free open-sourced
LibreOffice; based on opensource, compatible with MS Word/Office products.
See info pages + additional linked download pages for LibreOffice, here:

Maybe due to being a Stable 'longer used' version try LibreOffice 7.1.5.
(Not first one among macOS versions; should not balk w/ macOS 10.12.6x)

Then you may choose to make several backups via Time Machine; & clones
to have extra stuff ready for an upgrade to Mojave 10.14.6; on separate HDs.
