If it helps any, I occasionally get similar messages when trying to install a plug in. I have issues with NextGen and a zoom plugin for Woo Commerce. Most plugins install cleanly, but there is the occasional hiccup. If take the same plug in and install it a live site, no problem. Why? No idea. Sometimes I just us another plugin, if possible and go on. If I really need that plugin I will do make the changes once the site goes live.
It's frustrating, but for the moment the ease of use and portability of InstantWP outweighs the cons.
