I can only guess about this.

Under Win95 and above Winhelp.exe is a 16 bit shell that calls Winhlp32.exe,
possibly with some parameters that identify the help file.

Just to try to see what is going on try doing these two and see what the
results are:
  WinExec("winhelp.exe help.hlp", SW_SHOW);
  WinExec("winhlp32.exe help.hlp", SW_SHOW);

My guess is that it is not finding the help file and the generated error
message is inappropriate for the actual error (not an uncommon occurance
under Windows).

Also try putting the full path in the help file name given to WinHelp (don't
forget to double the backslashes and use short names).

I do not think *.chm files can be used in a 16 bit system.
