I’m on the latest C4d on Mac and after installing Corona v9 I got the message that the install failed. But everything looks like it succeeded, v9 works. I got the same message when installing the previous daily build of v9.
Exactly the same error at the end of the installation.
macOS 12.6 | Cinema 4d 2023.0.1 | Corona 9
I got the same, but everything seems to be fine. Whats the deal, anyone know?
Hi there, perhaps this guide may offer some insight?

Also, please feel free to test out the latest Corona 10 daily build as some issues have been addressed.
