I am using ArcGIS desktop 10.2 version and would like to import MasterMap Integrated Transport Network from Digimap to ArcGIS, So I was following the steps: 1 Install Productivity Suites v 3.4.1 2 import licence 3 Open OS MasterMap Data Converter. However, I got an error here about initialization error, which is shown below. 
I dont know what the problem is..Could anyone help here?
Many thanks!! Nancy
