Praticamente non riesco ad installare programmi con windows installer.Ho fatto la scansione con tutti i programmi possibili,c'era qualche virus ma non si e' risolto il problema.Non e' possibile il ripristino della configurazione perche' ho fatto la scansione in modalita' provvisoria.Non mi resta che controllare il log.Vi ringrazio
