Office 2007/2003 e MSCOMM32.ocx

Dopo l'aggiornamento KB969898 ci sono problemi ad usare il controllo da Access, per il momomento l'unica soluzione che ho trovato è rimuovere l'aggiornamento in oggetto. Il problema si presenta con il messaggio:

ENG: 'Object doesn't support this property or method'
ITA: 'Metoto o proprietà non supportati dall'oggetto'

Soluzione alternativa:

Internet Explorer was blocking the MSCOMM control. It likely does so for other activex controls that are installed from unsigned (won't pay a fee) projects.

HKEY_LOCAL_MACHINE\Software\Microsoft\InternetExplorer\ActiveXCompatibility\{648A5600-2C6E-101B-82B6-000000000014}

modify the compatibility flag to a value of 0.
