Python - OSError: [WinError 193] %1 is not a valid Win32 application when trying to use fluidsynth from mingus.midi

Question

I am Working on Windows 10 with 64 Bit. I want to use the mingus package for python in my jupyter notebook. But i have problems running the fluidsynth library.

I followed the instructions on this website to install fluidsynth: https://bspaans.github.io/python-mingus/doc/wiki/tutorialSetup.html

If i try to import fluidsynth with:

from mingus.midi import fluidsynth

I get the error:

---------------------------------------------------------------------------

OSError: [WinError 193] %1 is not a valid Win32 application

I dont know what the problem is. I already read some stackoverflow questions regarding this error, but i dont understand how i can fix my problem.

I am not sure if the fluidsynth, which i got from QSynth is used here.

Has anybody an Idea? Im not a very experienced programmer, so it could also be a small simple error.

Im glad for everybody who can help me!
