What you need to use
the Old English Aerobics Reader

A. Browsers

The new Reader is designed to work with Microsoft Internet Explorer version 6 and Netscape version 7 (also its cousins, especially Mozilla, the free, non-commercial browser on which Netscape is based). It probably will also work (displaying some cosmetic problems) with versions 5.5 of Internet Explorer and version 6 of Netscape, but I have not tested them. It makes use of several of the more recent features of these browsers, and so it will not work with older browsers such as Netscape 4.x.

A quick check of your browser suggests that it probably be able to run the Old English Aerobics Reader. Notes on individual browsers follow.

B. Fonts

Displaying or printing Old English requires several characters that are not in the fonts supplied with Microsoft Windows (though they are part of the Unicode standard on which these fonts are based). If some characters appear as boxes or question marks in your browser, download the free Junicode font, which should work equally well under Mac OS X and Linux. If you already have Junicode, you may have to upgrade, as characters are added to it periodically. Other fonts that will work include Victor Gaultney's excellent Gentium and George Williams's Caslon. Old English Aerobics will look for these (and any others I hear of) before it defaults to a standard system font.

C. Audio

To play the audio files in Old English Aerobics, you will need to download and install a Real Media player. The free version will do just fine. Search for it carefully on the Real.com page: the links for the pay version are understandably much more prominent than those for the free one.
