upgrading to cubase elements from AI

I got a UR22mkII and installed AI. I wanted to upgrade to Cubase Elements and paid for and downloaded the upgrade;
When I run the installer it tells me everything is already installed.
So is there no difference between AI and Elements? The product page enlists some other functions such as different guitar tones and AI is limited with regards to how many audio mixdown exports you can do. Or is this a matter of unlocking the already present features from the e-licenser?
Thank you for reading.
