Sword of Spirit

Hi all, I recently got a new Windows 10 system, and am trying to install the updates to Office 2003. I'm very glad I found this site, as I was having a hard time finding them. I do have a question though. How do I install that file? Windows 10 doesn't recognize it. Sorry if this is a bit of a newb question. I'm not completely tech illiterate, but I've never had to deal with something quite like this before. Thanks.
