OWC Component Cannot Be Create Using ASP

I have created an asp page that pulls data from SQL server and displays
on webpage in the form of Table and Chart.

I use OWC to generate Chart. It work find on my computer with Ms office
2000 installed, but when I upload my the page to my webserver, it
doesn't work with the following error message:

006~ASP 0177~Server.CreateObject Failed~Invalid ProgID. For additional
information specific to this message please visit the Microsoft Online
Support site located at: http://www.microsoft.com/contentredirect.asp.

Does anyone know how to solve this problem?

P.S. On the production server, Office Web Component had already been
installed. WSCript.CreateObject("OWC.Chart") works fine in my colleage's
vbscript file.
