Wait a minute: So what we are looking for is the first part of the product code?

So for instance:

Autodesk 3ds Max Design 2010: 495B1-05A141-10B4
AutoCAD Architecture 2010: 185B1-05A141-10B4
AutoCAD LT 2010: 057B1-05A141-10B4
AutoCAD Inventor Professional Suite 2010: 462B1-05A141-10B4
Autodesk 3ds Max 2010: 128B1-05B141-B009
Autodesk AutoCAD 2010: 001B1-05A141-10B4


... and use just the first 5 digits?
