You absolutely do NOT need to do a download to use SWM, unless you are trying to install an older receiver that has never been activated. Any SWM-compatible receiver that has been installed and running with a non-SWM system will run with SWM. And if for some reason the box is running very old non-SWM software (such as the software that was loaded at the factory on some of the H20 receivers) , the only way to get a download is to connect it to a non-SWM dish, download the software and then connect it to SWM.
