Unable to display Windows help files (.hlp) using Windows Vista

The information in this article applies to:

  • AIMMS 3 series using Windows Vista 
     

Summary

The Windows Help (WinHlp32.exe) program is no longer included with Windows operating systems starting with Windows Vista.

Introduction

Windows Help (WinHlp32.exe) is a Help program that has been included with Microsoft Windows versions starting with the Microsoft Windows 3.1 operating system. WinHlp32.exe is required in order to display 32-bit help content files that have the “.hlp” file name extension.

However, the Windows Help program has not had a major update for many releases and no longer meets Microsoft standards. Therefore, starting with the Windows Vista operating system release, the Windows Help program will not ship as a component of the Windows operating system.

Resolution

Users who want to view 32-bit .hlp files must download the program from the Microsoft Download Center, and then install it on their computers. Users who have not installed this program on their computer will be directed to a help topic in the Windows Vista Help and Support application. To download WinHlp32.exe, visit the following Microsoft Web site:

Discussion

WinHelp Macros are disabled by default (on Windows Vista); this means e.g. that automatic navigation to applicable topics is disabled as well. In order to enable these macros again some registry values need to be added or changed. Visit Windows Help Files can not run a macro on Windows Vista for more information.
