How to install addition module for an installed program?

I have installed theword , i have got the font and i have got additional module (exe file) that i want to add into theword to increase functionality / new purchased bible.
May i know how to do that ?

Thanks.

Just install it the way you installed theword (green run executable button).
I also tried it without a font and it seems to work since all I can see as texts are squares.
