AutoCADder

An often overlooked component of every AutoCAD box is Autodesk Product Manager (APM). This utility can discover and list virtually all Autodesk applications installed on your network. APM reports application names and versions, serial numbers, registration information and other important properties. Autodesk has released an update for this utility which extends the number of known applications - APM now recognizes also the AutoCAD 2006 family products, Revit 8 and Inventor 10.
You can find Autodesk Product Manager under
