Ciao a tutti, dopo una serie di modifiche fatte al mio pc (formattazzione e altro) vado a reinstallare tutti i miei programmi e con la versione Website 5 Evolution 10 all'avvio del programma stesso mi compare questo errore che mi impedisce il proseguo del lavoro:

18/04/2015 09:36:41 [EXCEPTION] Recupero della class factory COM per il componente con CLSID {56FDF344-FD6D-11D0-958A-006097C9A090} non riuscito a causa del seguente errore: 80040154 Interfaccia non registrata.

Se qualcuno può darmi una mano ringrazio veramente di cuore.
