Correct. Another set of careless chinese-style geniuses from Autel there.
The downloadable "update" does not tell anywhere which version/date/library it is, being entirely possible that the download may be the same the unit already has, or, even worse, an older one, as the Autel MS609 is declared "Old" in that same link.
So you would be forced to blindly download crappy .rar 33 megabyte compressed files that can end in update failure leaving the tool non-operational. And if you run only Linux like me; chances are nothing will work with 'Windows XP requiered' as somewhere hiding in fine print states
The Centech 60794 I just returned had "Burn" 02/26/13 ; Software ver 3.80 ; for Hardware ver 1.0 ; and Library ver 2.00
So a seven month old unit is already unsupported.
I wish to be wrong but found nowhere solid data telling that can be made to work with Disco 2
