Downloading and installing WINPLT on Windows7 and later Versions

Microsoft has made changes in Windows 7 and 10 that no longer allow the current WINPLT installation programs to function, Until this problem is resolved, you can install WINPLT manually as follows (this will, of course, also work for earlier versions of Windows if you prefer a hands-on installation): In another mean-spirited move Microsoft has decided that it will no longer support the WinHelp files used by WINPLT. You can install the needed support files for Windows up to 8 by following the directions in this link. Even more mean-spirited, Windows hlp files are no longer supported at all in Windows 10. Here is a Word.doc file that provides most of the functionality of the help file PLT71-Help-WORD.docx (it is a work in progress).
