Are you attempting to run the SWF file by itself, or wrapped in HTML?

Is the file saved locally, or on a server?
- Local file system access was disabled by default several months ago. See 'Disabling local-with-filesystem access in Flash Player by default' in Release Notes Flash Player 23 AIR 23 for more information
