• Addressed issue where applications based on the Microsoft JET Database Engine (Microsoft Access 2007 and older or non-Microsoft applications) fail when creating or opening Microsoft Excel .xls files. The error message is: “Unexpected error from external database driver (1). (Microsoft JET Database Engine)".

Microsoft will release and document an additional solution in a future release.
