Ho installato la versione Web Site 5 Professional 15 sul desk top e  qui funziona bene.

Ho poi installato da copia sul portatile seguendo lo schema stabiito.

Nel momento in cui cercavo di aprire un programma già fatto in parte, ma anche realizzando un nuovo programma mi dava un errore il cui testo allegato è il seguente:

Alla fine chiude il programma. Il programma è a 64 bit.

Qualcuno, per favore, mi sa dire che cosa è successo? Grazie.
