How to install WinHlp32 support in Windows 10

Some further info. Both .CHM and .HSX help files can be opened in 7-Zip. The listing that is displayed is all the parts of a Help file as individual files.

It looks like Microsoft has dropped support for the ancient hlp format (WinHlp32.exe) under Windows 10 completely.

I have found a solution to install an older version of "WinHlp32.exe" under Windows 10:

1. Extract the file "WinHlp32.exe" from a Windows XP installation (Windows directory)
2. Copy the file "WinHlp32.exe" to your Windows 10 system in folder c:\temp
3. Start notepad and create a new file with the following content:

@echo off
set crtpth=%CD%
takeown /f "%windir%\winhlp32.exe" >nul
icacls "%windir%\winhlp32.exe" /grant *S-1-5-32-544:F >nul
copy /y "%crtpth%\winhlp32.exe" %windir%
icacls "%windir%\winhlp32.exe" /setowner "NT Service\TrustedInstaller" >nul
echo.
echo Done.
echo.
echo Press any key to Exit
pause >nul
exit

4. Save the file as ""c:\temp\Win10-Hlp32-Fix.cmd"
5. Open a command prompt window as Administrator (very important)
6. Switch to the directory "c:\temp"
7. Start the batch file "Win10-Hlp32-Fix.cmd"

If all goes well you can use old .hlp files on your Windows 10 system afterwards. On my Windows 10 system it worked perfectly.

You may have noticed that Microsoft have introduced a new help format to replace "*.chm", and several vendors have started adopting it. It is called Help 2.

https://en.wikipedia.org/wiki/Microsoft_Help_2   Files have file type of ".hsx".  There are no conversion aides to this format, but it turns out they are just zipped *.CHM, so renaming them  back to "*.chm" makes them readable.

But,.... Read the follow-up article: https://en.wikipedia.org/wiki/Microsoft_Help_Viewer, which is likely becoming the new Help facility MS Help 3.x
