Retrieving the COM class factory for component with CLSID failed due to the following error: 80040154 Class not registered

Question

I have a web application which is used to send email. In this application, I am reading data from an Excel file and send email. This is working fine in the local system, but not working after uploading on the server.

I have received the following errors

Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error:

80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

How can I fix it?
