Generally help files are opened while running the program they are intended for. Those are not in a typical text file format where NotePad or another text editor can be used as a rule. Vista no longer supports the common hlp file used since 3.1. But MS now provides a Winhlp32.exe download for Vista available at http://www.microsoft.com/downloads/...D9-D3F5-4365-8070-334CD175D4BB&displaylang=en
