What setup?Its just a zip package livestreamer-latest-win32.zip and now just unrar this package anywhere = folder name livestreamer-v1.10.2-43-gdf62756 and inside you have all files so there is not setup needed.Go into this folder put your rtmpdump.exe and CMD.exe into and then start the CMD and enter the link data.Thats all.
All new files are in this package already...
Code:
\livestreamer-v1.10.2-43-gdf62756\livestreamer-1.10.2-py2.7.egg\livestreamer\plugins
...into this you find the files.
