Caro Alfonso,vedi se puoi aiutarmi in questo problema,ho scaricato e installato piu volte Yahoo Messenger, ma non riesco ad aprirlo,ne dal desktop ne dalla barra di avvio veloce,forse nel mio sistema manca qualche cosa indispensabile per aprire questo programma,questo non succede con Alice messenger e Windows Live messenger che li utilizzo normalmente,ti allego il mio LOG così potrai valutare la situazione,ti ringrazio anticipatamente.
