Unable to Download Airi Theme

I get the following error message when I try to upload Airi Pro into my themes in Word Press. Please advise. Thanks.

Unpacking the package…
Installing the theme…
The package could not be installed. The theme is missing the style.css stylesheet.
Theme installation failed.
