In which folder should I put these files ? and how to install the .zip folder please?

Sorry.
I have SketchUp8,
I Fixed the specifications in the profile.
I understood, I was able to change the object and use the Tool Subtraction.

I would instal the plugins Inspector2

The file is not executable.
Error
