Looks like there are 3 diffrent Galaxy receivers all look the same apart from name on top right front of receiver.

One has HE@D digtal Galaxy another MEDI@LINK and another CHALLENGER.

The 3rd party software for the Medialink does not work in the Head, so I take it all software for these receivers are diffrent, but they are called
after unzipping ' total flash.abs'

Confusing
