Rhinovault installation


I tried to install rhinovault on my device yet wqithout any succes. Followed throughly the readme file, however whenever I try to add the rhinovault.rui file it says the the root file is missing. I am quite lost asI followed step by step the installation instruction however nothing seems to work in terms of installation of the plugin…
The ironPython is installed as far as I’m concerned (2.7.7) yet the command _rvFormTri is uknown.
Even tried reinstalling rhino and nothing seemed to any good . Are there any option for installing the plugin ?
