Symptom
The Mac OS X Help Viewer reports "The Specified HTML File Could not Be Found" when a Help topic is selected.
Solution
Remove any solidus ( / ) or trademark ( TM ) characters from the name of the Mac OS X hard disk or partition. You can substitute another character, such as a comma, ampersand, or underscore. If this issue occurs with any other alphanumeric character, particularly í, é, á, ú, ö, ü, or ö, try removing it as well.
