After some faffing around, I managed to get Musescore4 installed. It 
appears that Musescore4 will not correctly read the output of its  own

In view of that, the import to Lilypond, although it works, for some 
value of "works", is not terribly useful. Thank you for your suggestions.

Further research is required.
