This is where I tell you to use google rather than ask me to google for you.
Both the registry thing and your missing file is something others have already encountered, asked about, and had answers to.
You've got fairly small obstacles for both installing the binaries (registry problem), and for compiling it yourself (vcvarsall.bat) both of them are most likely not difficult to google through.
A third route, even though you don't really need a third, is using linux instead, these things often come easier there.
Googling will tell you to install visual studio to get a compiler. If that's overkill, go back to trying to fix the registry. Or use linux where installing this is a single command and that's the end of it
