bool python script refuses to show up in addon list or install properly

hi folks, I am trying to get the bool script installed 0.3.2 by vitio balbio and michail rachinskiy.

no matter how I try to install it, the plugin doesn´t show up in the addon list after install from file (save user setting isn´t a problem here)
it just doesn´t show up, and if I try to install in the c users app roaming data, it get´s error on path, tried install on program folder directly to…but nada.
I have a few other scripts, like manual bastionis human creator, but this doesn´t work.

Anyone knows why it refuses to show up or install properly?
I am using blender 2.78b on windows 7

cheers
Michael
