#31 MTF edge and bead analysis fails

[Angela Maldera]

I'm trying to evaluate the Edge MTF on a 2D-synthetic DBT image but it fails reporting the following error:

System.TypeInitializationException: The type initializer for 'IQWorks.ProcessEdgeLine' threw an exception. ---> System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {18C8B662-81A2-11D3-9254-00E09812F727} failed due to the following error: 80040154.

Any suggestion? It also fails in the MTF bead analysis for the Catphan phantom.
