[Risolto] Beamer: installazione e funzionamento

Buongiorno,
devo creare la presentazione per la discussione della tesi e ho pensato di farla utilizzando Beamer. Premettendo che utilizzo WinXP, MikTeX 2.9, TeXnicCenter 1.0 Stable release candidate 1, ho scaricato attraverso il MikTeX Package Manager (Admin) il pacchetto Beamer.

Ho provato a compilare gli esempi presenti ma non ho nessun output tranne il seguente file:

Ho provato a esegure degli esempi tratti dalle varie guide ma in tutti casi non ho segni di vita e non produce le presentazioni.

Cosa devo fare per far funzionare il pacchetto??

Ps: Ho visto che nella cartella C:\Programmi\MiKTeX 2.9\tex\latex\beamer\base,oltre a diverse cartelle e diversi files *.sty, c’è un file LaTeX class denominato beamer che viene aperto con un programma chiamato TeXworks ma, se lo compilo, crea solo errori. E’ questa la fonte dei problemi?
