It comes as sources only and requires cuda 8 toolkit to be installed (( My nvidia developer subscription is expired so I cannot download cuda 8 RC and build new nanashi version ((
That's weird as I wanted the sources and downloaded the windows binary instead by mistake.
use the link to OneDrive above but cancel download. Then choose the last download in the list from OneDrive. There will be 1.8 r2
shame on me ... found some binaries ... will try
