**For Windows**:
To build the Windows executable, you must have pyinstaller (and optionally mutagen, pycryptodomex, websockets). Once you have all the necessary dependencies installed, (optionally) build lazy extractors using `devscripts/make_lazy_extractors.py`, and then just run `pyinst.py`. The executable will be built for the same architecture (32/64 bit) as the python used to build it.
