An advertised or Install on first use install state was selected for the most current version of Access on the computer. If a database is double-clicked in Microsoft Windows Explorer, an attempt is made to open the database using the HKLM_CLASSES_ROOT registry settings for the last version of Access installed successfully. Since an advertised instance of Access is not installed yet (all the registry entries and executable files are not yet present) users may attempt to open a newer (converted) version of an Access database with an earlier version of Access. The user should run Access once by double-clicking the advertised icon to install the advertised version fully before attempting to open a converted database.
