I just purchased an E4401B for my Ham Shack.  It had bad memory and battery.  I replaced both and it works.  However, I need to do a processor initialization.  I downloaded N7811A ESA Series Calibration Application but its asking for a "Key".  How can I obtain this software key?  Thanks for the help!
