if it is not there it is not installed.

use our sketchucation tools to install it.

Plugin Store Download | SketchUcation

Extending SketchUp has never been easier with a suite of tools that make installing and disabling plugins and extensions a one click operation.

As Box says it has a dependency library it needs to run

YES!!! That helped me out thanks!
