EDIT:
Okay I figured it out, same solution as above, but in the installer you have to click "CUSTOMIZE" in the bottom left, when you get to the installation location. If you dont click there all you can choose is which HD to install it to.
So you have to click there, check the R18 folder, but then you have to click on the folder and choose "custom" (i think), and navigate to your C4D demo folder. Then it will work.
im having the same problem.
latest demo of Cinema4D, and latest corona for cinema4d OSX..
After installing, when I start cinema4d, there is no corona in the renderer list.
Where is Corona installed anyways? I cant find any folder for it anywhere. I've done a full search on the whole HD, and all it finds is a Corona folder in Macintosh HD/Library/application support/corona/ but the only thing that is in there are LUT's.
When I run the Corona installer, I dont get a choice to manually choose where to install it. Are you running Corona Cinema4D A6.1.pkg?
I've tried both that one and the A6.2
Im on OSX Sierra.
Thanksful for any help
