Figma to Webflow: Installing Octane for Cinema 4D (bonus lesson)

I’m excited to start this course but Octane does not offer a free trial for Octane Enterprise PR13, only PR11. I can’t complete the step from the bonus lesson on setting up C4D and Octane; the part about dragging the plugins because I don’t have c4doctane-R25 in the Octane folder.
I’d really like to complete this course but not sure if I’m ready to spend so much money on a subscription of C4D and Octane.
