You can still use the version 1.1 of the plugin, as long as you don't use DAE/Collada 3D models in you plan.
Take care of removing more recent files starting by AdvancedRendering from your computer to ensure the version 1.1 of the Adcanced rendering plug-in is the one that will run, because Sweet Home 3D always chooses the latest version of a plugin when there exists more than one file of a same plugin in plugins folder.
