Product Activation license error 9.1.4 and 15.1.54

Error [9.1.4] displayed in the Product Activation dialog is mostly a result of a prior "Error [15.1.54]".

Error [15.1.54] (displayed after the message: License Error/The license file for this product has been deleted) is caused by modifying/corrupting of the .DAT file in Documents and Settings\All Users\Application Data\Autodesk\Software Licenses or this file is inaccessible.
