Libfredo6 Installation problem

Libfredo6 is installed but it is not showing the source to install plugins ins, am using windows10_64 Bit OS,64GB RAM and 5 GB graphics
I have installed the Libfredo6 through Sketchucation Extension store

Libfredo is a helper file, needed to run other extensions, but it does nothing on it’s own.

what should i do for installation of this libfredo6 actually I need animator plugin,
I followed the correct process for the installation.

Install the animator extension the same way.

Also restart SketchUp after installing.

Please watch there in extension manager author is not visible
