sewlady, you shouldn't need any of the office programs to install and use the fonts. You can simply use them in WORD!
just in case, to get to word,
Click on start/windows icon in lower left corner
click on all programs
click on or scroll over accessories
then there should be a program called either WORD or WORDPAD click on and that you can use it to type the name, then change the font, and change the size of the letter. For a name pillow I normally set my font to between 300-500 to change the number this high you have to type the nubers into the size bar!
If you need more help let me know!!!
