In addition to acquiring and using fonts installed with other applications, you can download fonts from the Internet. Some fonts on the Internet are sold commercially, some are distributed as shareware, and some are free. The Microsoft Typography site site provides links to other font foundries (the companies or individuals outside of Microsoft who create and distribute fonts) where you can find additional fonts. After you find a font that you would like to use with an Office application, you can download it and install it through the operating system that you are currently using on your computer. Because fonts work with the operating system, they are not downloaded to Office directly. You should go through the system's Fonts folder in Windows Control Panel and the font will work with Office automatically. On the Mac you use the Font Book to add the font and then copy it to the Windows Office Compatible folder. Many third parties outside of Microsoft package their fonts in .zip files to reduce file size and to make downloading faster. If you have downloaded a font that is saved in .zip format double-click the zip file to open it. Once you've downloaded the font you want to install you need to install it in the operating system. Once the font is properly installed in the operating system Microsoft Office will be able to see and use it. For detailed instructions select the operating system you're using from the drop-down box below. Find the font file that you downloaded, keeping in mind that it may be contained within a .zip file. It's probably located in your downloads folder. Double-click the font file to open it in the Font Previewer. If you're satisfied that this is the font you want, click Install at the top left. Close the Font Previewer, and open your Office program. You should now see your new font included on the font list. Find the font file you downloaded - it likely has a .ttf or .otf extension and it's probably in your downloads folder. Double-click on it.
