I found this at http://www.biblicalgreek.org/links/fonts.php
"Minion Pro - This font is a wonderful professional font that used to cost $100 but is now available free with Acrobat Reader version 7. To get the font, install Acrobat Reader version 7 then look in the resource folder where acrobat reader was installed. It will probably be at this address on your computer: C:\Program Files\Adobe\Acrobat 7.0\Resource\Font. You will see the Minion files. You still must install the fonts so your system will recognize them."
The above is not my wording; it is from the web site referenced above.
