joshtynjala You can follow Adobe's instructions for updating the AIR SDK inside the Flex SDK. The Feathers SDK is a fork of the Flex SDK, so the process is the same. https://helpx.adobe.com/x-productkb/multi/how-overlay-air-sdk-flex-sdk.html Be sure to use the version of the AIR SDK that does not have a compiler.
