When the [Help | Contents] Menu is clicked, the following error message will be displayed on the screen:  

Windows help files (*.hlp) are opened with the winhlp32.exe installed in \WINDOWS folder.  Unlike previous Windows versions (98/2000/XP) of this file, the Windows Vista version of the winhlp32.exe file (9,216 bytes) is only a dummy file.   

The Windows Help (WinHlp32.exe) program is no longer included with Windows operating system starting with Windows Vista (Knowledge Base, KB917607).  Microsoft released an optional update (click here for further information) on March 9, 2007.  We visited this Microsoft Web site, downloaded the update, and installed the update following the instruction.

Installation of the this update replaced the dummy winhlp32.exe file (9,216 bytes) with a Vista version of WinHlp32.exe file (296,960 bytes).  After update, we found that ZSimpWin Windows Help file was displayed on the screen, however, hyperlinks to an email address and a Web page did not work.

The XP SP2 version of winhlp32.exe file (283,648 bytes) and Windows Vista version of WinHlp32.exe file (296,960 bytes) are different. It was found that the XP SP2 version of winhlp32.exe worked properly as intended.  Because of file protections in Windows Vista, it requires some efforts to replace the buggy Vista version with the XP SP2 version (283,648 bytes). 

1.   Obtain a copy of the XP SP2 version (283,648 bytes) from a working XP PC.  You can click here to download this file.

2.   Follow the instruction published at this site, to replace either of the Vista versions (9,216 bytes or 296,960 bytes) with the XP SP2 version (283,648 bytes).
