In All Drupal themes packages created by OrdaSoft you can find Drupal theme file. Drupal theme installation via extension should take no more than one minute.
You need to go to your Drupal admin area, type in your browser http://your site/?q=user, enter Drupal administrator Login and Password. If Drupal 7 will be activated clean URLs, then the path will be the http://your site/user
From the backend of your Drupal 7 site (administration) select Appearance -> +Install new theme. Click the Browse button and select the theme on your local machine. Install from a URL - copy the address of the theme for installation. So you can download directly to your theme directory your site/sites/all/themes, and it will appear in the administrative block.
