RX 10 Elements and RX 11 Elements are now collections of plug-ins and no longer include the audio editor application. This is because we learned from in-product analytics that most of our Elements customers like to work directly in their DAW via plug-ins.
If you would still like the application, it is included with RX 11 Standard and Advanced along with the existing Elements plug-ins. Please see the RX 11 comparison chart on our website for more details on features included in RX Standard and Advanced.
