My guess is that those are the old format help files that Microsoft no longer supports. You used to be able to apply a special patch in Windows 7 and Windows 8 to use those help files, but Microsoft dropped support completely from Windows 10 (no patch available). If you are running Windows 7 or 8, PM me and I can send you the patch file.
