.js Plugin does not appear in plugin manager

Hi All,

i just downloaded some fingering plugins (https://musescore.org/nl/project/saxfingering) i downloaded the plugin, unziped it and copied sax_fingering.js into C:\Program Files (x86)\MuseScore 2\plugins.

restarted Musescore 2.02. plugins > Plugin Manager but that the plugins do not appear. All qml plugins appear but the .js do not. i also tried with other plugins and all with the same results.

can anyone help me out?

Martijn
