If you wish to work on a project over two different machines, one on "Computer A" and other one on "Computer B", you can deactivate your license from your "Computer A" and reactivate in your Computer B" (and vice versa). 


To deactivate your license, close Cinema 4D. Shutting down Cinema 4D will release the license from your computer. Then you can reactivate another machine just by using your Sign-in credentials (for further help see this section). 


If you wish to run Octane on more than one computer at the same time, you will need to purchase an additional license to do so.


You can learn more about licensing questions by referring to the FAQ document, located here


Start up Issues with Cinema 4D®

Should you run into any issues with Cinema 4D failing to launch after installing the c4doctane plugin, delete the “otoy_credentials” file from the file locations listed below; then try again to restart the application and sign in procedure.


Windows: %APPDATA% > OctaneRender > otoy_credentials


Additionally, you can run Octane Standalone and sign-out from the account section in that application.
