Unfortunately, we have encountered a problem with the Cineware for Illustrator V1.3.00 plug-in that can lead to problems when using it, which requires your action, if you are not an owner of a Cinema 4D License.
This affects the installations on macOS and Windows.
After installing the Cineware for Illustrator V1.3.00 plug-in, please open the menu Window - Cineware - Preferences in Illustrator.
Change the path there from Cinema 4D (.app/.exe) into Cineware (.app/.exe) as shown:
After changing the path, you need to restart Illustrator.
