I am getting a 2 Hopper/2 Joey system installed tomorrow. The installer has already given me all the hardware, and I had previosly verified (by borrowing a Hopper and Joey) that all locations in my house have suitable wiring for the installation. My questions is, can I download the initial software update to both Hoppers this evening so that they are ready to install tomorrow? I know not to even touch the Joeys until everything is activated and showing live TV, but I am just looking to save some time for my installer. I just don't want to get the Hopper into a state where if I unplug it or don't touch it for 24 hours (when activation will occur) it will screw something up. Thanks!
