Installing Xywrite

We have editors that still use Xywrite word processing. I have recently reloaded a pc with 98 and have no idea where to begin with installing Xywrite. And unfortunately for me the other support tech’s don’t have a clue. I’ve tried searching google but so far I haven’t come up with any answers. I would really appreciate any pointers, guidelines or instructions anyone might be willing to share.
Thanks!
