zlib.dll is missing in your Windows release #876

I downloaded this release, unzipped it, installed Java 8, launchClient works, but in the Python_Examples python tutorial_1.py failes with ImportError: DLL load failed: The specified module could not be found.

depends.exe shows your binary is dependent on zlib.dll:

But this is not found in the downloaded zip. I noticed your build from source actually builds zlib from source, perhaps you should included the built binary in your release zip file?

I'm pretty sure I'm also observing this problem. (edit: I built zlib myself and moved it into place and now things are working, so I'm even more sure that this was the problem.)

Here's the DLL if anyone finds it useful. zlib.zip

This worked for me as well. Can confirm the pre-built binary for 0.37.0.0 Python 3.7 does not work without zlib in the PYTHONPATH alongside the 'MalmoPython.pyd' file. This was used with the PIP python wheel for Windows 0.37.0.0 on Python 3.7.
