Hi, I am new to Sketchup and installing plugins and extension.

I'm unable to install the ruby Script in my Shetchup 2016. The plugin isn't loading. I have copied and dragged the file into my Plugins folder. Path - /Users/Praveen/Library/Application Support/SketchUp 2016/SketchUp/Plugins

Looking for some kinda guidance from the community on what I've done wrong
