Go to root WHM / Plugins / RVManager / RVSiteBuilder Manager. On the Manager homepage, if you are not on the latest version, it will show you the link 'Upgrade to latest version'. Click the link to update your RVSitebuilder version.
If you prefer doing on SSH, you can run the following command.
perl /usr/local/cpanel/whostmgr/docroot/cgi/rvsitebuilderinstaller/autoinstaller.cgi
