i have a web service that reads data from excel using Microsoft.Office.Interop.Excel. It works fine on my local machine but when i upload it on a server it gives the following error

Server was unable to process request. —> Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005.

i googled and tried to follow the suggestion of DCOMCNFG-> component services-> computers-> my computer-> com+ appications but then i dont find the Microsoft excel to change rights.
Office 2003 is installed in server and file i am trying to open is 2003 too.
Please help!!
Thanks

    You won’t find Excel, you’ll have to find the matching CLSID and alter the Activation/Launch permissions.

    Standard Disclaimer: Unattended execution of office on the server is not recommended by Microsoft, but a lot of us do it happily (myself included).
