If you’re willing to trust another person’s file (that person is me, if it matters) I placed my working mfplat.dll file on my web server:
https://www.timekills.org/public/mfplat.zip
(Update 18 SEP 2019) This DLL is from Windows Version 1703 (OS Build 15063.674) 64 bit. It does work on new Windows versions up to at least 1903.
When I moved this file from my Windows.old into the new c:\windows\syswow64 directory PMS did start working again.
