Problem loading AutoTrack into MX v8i

I can’t seem to install AutoTrack into MX SS2. I’ve had this running in the past but can’t get it going on my new laptop. Has the procedure changed? The last time I installed it via: 

CAD > Utilities > MDL Applications and Browsed to C:\program Files\Autotrack\LoaderV8\atrack.ma

But now there is no LoaderV8 directory or atrack.ma file.

I’m running V8i SS2 08.11.07.427 and AutoTrack 8.9a (Build 20100528)

Does anyone have any ideas how to get this running?
