Purchased a broken theme

Good Morning,

Yesterday I purchased the “Constructo” theme. I downloaded the theme .zip and uploaded it to my WordPress website. However the theme installation failed producing the following error.

Installing theme from uploaded file: constructo.zip

Unpacking the package…

Installing the theme…

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

Theme installation failed.

After attempting the installation, I unzipped the folder and checked the contents and the style.css stylesheet is not in the folder.

Hi there

Its a HTML template and can not be installed in WordPress as a theme
