  Hi there,

  A little update. I managed to get OpenSesame to run. For anyone else who may be doing the same as me, you need to also follow these instructions (https://osdoc.cogsci.nl/4.0/download/) in order to download appropriate packages. Using anaconda I also installed and ran the following code:

  conda config --add channels conda-forge --add channels cogsci
  conda install opensesame opensesame-extension-osweb opensesame-extension-updater opensesame-plugin-psychopy rapunzel pygaze qtconsole pyqtwebengine wxpython
  pip install soundfile pygame http://files.cogsci.nl/expyriment-0.10.0+opensesame2-py3-none-any.whl
  pip install psychopy psychopy-sounddevice
  
  # I also installed:
  pip install opensesame-plugin-media-player-mpy
  

  Now when I run

  conda activate opensesame-py3
  opensesame
  

  in the anaconda prompt it runs Opensesame as expected which is great. However, I now have another issue when I try to run my experiment:

  Traceback (most recent call last):

  TypeError: arguments did not match any overloaded call:

   save(self, fileName: str, format: typing.Optional[str] = None, quality: int = -1): argument 1 has unexpected type 'QBuffer'

   save(self, device: typing.Optional[QIODevice], format: typing.Optional[str] = None, quality: int = -1): argument 1 has unexpected type 'QBuffer'

  
  

  I have noticed someone else here looks to have a similar problem (https://forum.cogsci.nl/discussion/9299/arguments-did-not-match-any-overloaded-call). Would anyone be able to figure out why this is happening?

  Cheers,
