How to install missing DBNamespace 1.0 Type Library
 

Hi,
When I try to run the Excel 2000 workbook with macros at PCs with Office
2007 or Office 2003 I got error "missing reference or library". In Reference
Dialog are marked as "Missing" DBNamespace 1.0 Type Library and MSCalendar.
I am using Vista Ultimate with Office 2007 and XP Pro. with Office 2003.
How can I get missing library?
