Who/What wants you to remove Norton 360? Maybe, new installer removes currently installed Norton…before installing Norton 360. Meaning, new installer acts like Norton Remove and Reinstall Tool. Maybe, your current Norton is v22.x and new Norton is version v24.x. Have you registered your new subscription with your Norton account?
it wants to transfer the authorization to only 1 machine, do I need to reinstall. I’ve been using Norton for decades this the first time it’s done this.
