Download Pyro 4 (4.30) tar.gz fie
Extract Pyro 4
Change to the extracted folder for Pyro 4.
Install Pyro 4 - ipy.exe setup.py install

2. [New issue] ssl default to SSL v2
User paweljasinski has proposed the issue:

"ssl connections defaults to SSL v2. cpython 2.7.8 under linux, cygwin and win32 defaults to TLS 1.2
This causes 
IOError: System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host

during the initial handshake (server drops connection right after Client Hello)
