OSError: cannot open resource

I'm running Python 3.8.6 on Windows 10x64, version 2004 and I'm getting the following error:

I did a fresh reinstall of Python for this and these are the packages I currently have:

I see, this seems to be related to windows not finding the font. If you want to fix that go ahead, I don't have windows here to test, but if I find the time I'll look up how its done properly. https://github.com/MatthiasLienhard/flowkey_dl/blob/f23754d4c114120c93456d5eea51166a550d5068/flowkey_dl/flowkey_dl.py#L80

I removed the path, and it still seems to work on Ubuntu, maybe it works on windows now. https://github.com/MatthiasLienhard/flowkey_dl/blob/a58e26794ecf9bc4b49105b4b7f81473e25a2656/flowkey_dl/flowkey_dl.py#L80

I assume its working

fabiorzfreitas commented 3 years ago

I'm sorry, I never got to test the fix and in meantime I now don't have a flowkey subscription anymore.

Nevertheless, this may help you: I looked into my system folders and they didn't seem to have FreeMono amongst the fonts. Downloading it from somewhere else and properly installing seemed to solve part of my problems, but it all ended up failing somewhere else (in the download process).

Thank you for your support!
