hardware_tablature plugin

Hello all,

i am triing to install the Hardware_tablature plugin but cant't succeed.

I extracted the ZIP file lasconic_hardware_tablature in:
C:\Program Files (x86)\MuseScore 2\plugins\lasconic-harmonica_tablature-9541fad

I then activated it in the Plugins Manager menu.

I could see it in the Plugins menu, but when I select it, the window is empty (see attached)

I am runing Musescore 2 in window 7

Thanks in advance for your help
