I have been using a student version of Cinema4D R21, along with Corona installed. I just got a new 6 month student subscription and they gave me a license this time for Cinema4D R23, and it came with its own installer. I have successfully installed the new Cinema R23. Now I see Corona is no longer showing up. How do I switch Corona from my old inactive Cinema4D R21 to my new Cinema4D R23? Do I have to uninstall or remove it and then reinstall it somehow?? Thanks.
