Installing the module is no different from any other Joomla! package. Go to the My Downloads Page; you’ll find there a file called mod_web7_video.zip, which contains the core Joomla 3-compatible module files. Download this file.
Head over to the Joomla Administration and go to Extensions -> Manage -> Install. Now you can drag&drop mod_web7_video.zip and Joomla will do the rest.
