[QGIS-it-user] Quale modulo mancherà per plugin Cxf_in?

[Pontigia Fabrizio]

Buongiorno,
ho installato Qgis 3.0 e Qgis 2.18.18 su windows Seven utilizzando Osgeo4w.
Ho riscontrato diversi problemi (es.  l'installazione "Express Web-Gis 
crasha quasi subito, ma pazienza), vorrei poter utilizzare il plug-in 
Cxf_in.
Attualmente all'avvio di Qgis 2.18, ottengo il seguente errore:

            ImportError: DLL load failed: Impossibile trovare il modulo 
specificato.

Non capendo quale modulo manchi, non so come risolvere.
Mi potreste aiutare?
Grazie
Buona giornata
