About Microsoft Office Web Components
Microsoft Office Web Components is a set of ActiveX controls installed with either Microsoft Office 2003 or any Office 2003 application. With Office Web Components installed on your computer, you can interactively use a spreadsheet, a PivotTable list, and a chart on a Web page in Microsoft Internet Explorer 5.01 with Service Pack 2 (SP2) or later.
If Office Web Components is not installed on your computer but you have a valid Office license that permits intranet distribution, you can configure the components so that users will be prompted to download Office Web Components from your corporate intranet. This allows users at your site to use a data access page without having Office applications installed on their computers.
For information about how to configure Office Web Components, see the Microsoft Office 2003 Resource Kit.
