title: Umbraco - web.config issue when installing
body: <p>I'm trying to install a default Umbraco installation on IIS7, and I'm getting the following error on my (unmodified) web.config file, any ideas?</p>
  
  <p><strong>Config Error
  The configuration section 'system.web.extensions' cannot be read because it is missing a section declaration</strong></p>
  
  <p>Thanks,</p>
