Have working CDF.
Install Autodesk 2014 bundle.

There are three of the Autodesk software's that is causing the issue. Issue appears to be with the SP1 and HF1 versions of the Autodesk. This means that the versions of Autodesk that return invalid data will not have good information in the inventory reports. This needs to be reported to Autodesk.
Have to handle these invalid charterers by preventing being added to inventory scan (xml file, also referred to as wif file) scan.
