ConduciveMammal on "[Plugin: Orbisius Child Theme Creator] style.css stylesheet missing"

Hey,
I'm trying to install Orbisius Child Theme Creator on my self-hosted site but when I try to install directly from the .zip file, I get this error message:

Unpacking the package…

Installing the theme…

The package could not be installed. The theme is missing the style.css stylesheet.

Theme install failed.

How do I go about fixing this?

Thanks
