It's not a video, It's a .EXE file. Using that file on a Mac, you need virtualization software.

Their site states under - Products:
'The latest editions are covering all 1991 - 2011 Mercedes- & Sprinter vehicles and 1988 - 2010 BMW- and Mini vehicles.'

Then under - BMW & Mini Coverage Version '10':

'Vehicles*:

1 Series - E81 - E82 - E86 - E87
3 Series - E30 - E36 - E46 - E90 - E91 - E92 - E93
5 Series - E34 - E39 - E60 - E61
6 Series - E63 - E64
7 Series - E32 - E38 -E65 - E66
8 Series - E31
X1 - E84
X3 - E83
X5 - E53 - E70

*) the functions and coverage of the above listed vehicles may vary, depending on the type and year of the vehicle.'

Why write E53 when it might not be supported? I find it very fishy indeed, hope you get your money back or that they finally deliver what you paid for!
