Error when using mne_make_movie

Hello,

I'm trying to use mne_make_movie to extract .w files. However, I am getting
an error message when calling mne_make_movie (reproduced below). Any idea
what might be causing this error?

Could this have something to do with the 64-bit libraries I'm using?

Thank you in advance for your help.

Michael

--picknormalcomp --subject 409 --smooth 5 --fthresh 5 --fmid 10 --fmax 15
--w test

Here is the error message:
