You will need the version 1.0.8 of Butterfly Effect or later to authorize it to your local machine. Download the latest version here and run the installer. Log out and back in to your account in your iLok License Manager. Select ‘All Licenses’ at the top of License Manager, or search for Butterfly Effect. If you see the local machine option, you can go ahead and authorize it. If you don’t see the local machine option and already have Butterfly Effect authorized to your iLok cloud or key, de-activate the cloud/key authorization. You should then see the local machine option. If you still don’t, log out of License Manager and back in, and it should show up. After you authorize Butterfly Effect to your local machine, we recommend logging out of License Manager and back in before launching your DAW. Launch your DAW. Butterfly Effect should show up and be authorized. Note – Local machine authorization option is available only for full licenses. It is not available for the demo.
