You may or may not need to do all the following. From a message I posted in October 1999:

On older computers that do not have IE4 or later, this is what I had to do to get HTML Help to work in VFP applications.

First, download the HHUPD.EXE file from MS. Select the correct language to download.

I then created a small VFP executable for each user to run. The code is as follows:

set talk off
set safety off
copy file foxhhelp.exe to c:\windows\system\foxhhelp.exe
copy file foxhhelpps.dll to c:\windows\system\foxhhelpps.dll
run /n foxhhelp /regserver
run /n hhupd.exe

Change the paths above for NT workstations as needed.

I then place the EXE, foxhhelp.exe, foxhhelpps.dll and an empty foxuser.dbf/fpt file all in the same folder. The foxhhelp files are in the VFP Home() directory. Tell the user to double-click the VFP executable you create from the code above.

Then in your applications all you have to do is include a line early in your main PRG --

SET HELP ON
SET HELP TO MYHELP.CHM
