That is correct, the Windows binary is an online installer. The reason for this is that fman uses Google Omaha for its auto-update mechanism [1]. The Arch package is smaller because it declares PyQt as a dependency, rather than shipping it itself. The reason for this is that it was difficult otherwise to make the shipped version of PyQt libraries and dependencies compatible with the ones already on the system.
