Dreamweaver CC is available as part of Adobe Creative Cloud for as little as $20.99/month (or $9.99/month if you’re a previous Dreamweaver customer).

Adobe Dreamweaver CC allows you to design, develop, and publish for web and mobile platforms without getting buried in code. Dreamweaver provides an intuitive visual interface for website creation and editing and offers up-to-date compatibility with web standards as well as first-class support for HTML5/CSS3 and jQuery.

Note: The downloadable file is an installer that will install the application when opened.
