AutoCAD 2013 to AutoCAD 2014 migration with .NET Application getting Exception

We have a .net application where we have referenced AutoCAD 2012 Type Library and Autodesk.AutoCAD.Interop.Common(18) (Both COM type objects)

Now we are expected to migrate to Autocad 2014 We have changed the reference to AutoCAD 2014 Type Library and Autodesk.AutoCAD.Interop.Common (19) (Both .net type objects)

We do not get any Build error but when execute the application we get the error Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)). Are any additional measures needed for a migration from AutoDesk 2012 to 2014
