midi2ly dll error

[Gianmaria Lari]

Hello,

When I try to convert from Midi to Lilypond using Frescobaldi I get the following error:

The file couldn't be converted Error message:

Traceback (Most recent call last):

File "C:\Program Files (x86)\LilyPond\usr\bin\midi2ly.py", line 54, in ? import midi

ImportError: DLL load failed: The specified module could not be found.

Any suggestion to fix it?

Thank you, g.
