Download to hard drive

logon as that profile

let wizard run, selecting don't connect to internet and automatic
unplug and replug the zydas usb adaptor
zydas launches itself. click on icon in system tray (right hand end of task bar)

Not sure how much of this process with user profiles was necessary - but it worked for me.
