For businesses, using unlicensed software can lead to heavy fines and legal action during a software audit.

Unlike a Serial Number, which identifies your specific license, a Product Key identifies the specific software product you are installing. For example: 001H1 AutoCAD Architecture 2016: 185H1 Autodesk Revit 2016: 829H1

Using the incorrect key for your specific version will result in an activation error, even if your serial number is valid. What is kuyhaa?
