You must have the latest version of Silverlight 4 installed. If you don't, there will be a link to install it where Rawr should be.
If you've installed Silverlight and still don't see Rawr above, make sure you've fully relaunched your browser, and are not running IE-64bit (use 32bit). If that doesn't work, uninstall and reinstall Silverlight.
