-These instructions are tested with Python 2.7, but should work with 3.x as
-well. You may be able to substitute ``easy_install`` with ``pip install``.
+If ``pip`` is not available on your system, you may need to install it, either from a package manager or by running ``python -m ensurepip`` from the command-line. If you can't use the regular pip comamnd, ``python -m pip <command>`` works too.
 
 Windows
 -------
-The best way I've found to install Pyinstaller is to first install setuptools_,
-manually install pywin32_, and then run ``easy_install pyinstaller`` from
-the ``Scripts`` directory in your Python installation.
+PyInstaller 4.8 introduces a hook script which will break DFHack. A `bug report <https://github.com/pyinstaller/pyinstaller/issues/7118>`_ already exists for Pyinstaller for this issue, but at time of writing, it's still an issue. For now, use an older version; anything from 4.2 to 4.7 should definitely work; 4.6 is being used for the official builds. Use ``pip install PyInstaller==4.6`` to install that one.
