I'm just an amateur at this myself but have used Word as
my E-Mail editor for a while now.
Try this.
click on Start in the lower left of your screen.
Click on Control Panel.
Click on Internet Options
Click on Programs
Under HTML editor "arrow"  down to Word. I have a choice
of Word or Wordpad.
Hit OK and you should be set up to use Word as your E-Mail
editor.
Hope this works for you.
A late thought here is to tell you that I always set up a
new "Stationary File" by editing (in Word) an already
existing file that came with the program and saving it to
my own named stationary file.
