Object not valid or not registered error?

I have created automation process using console application. The app reads
emails in outlook’s inbox folder, saves attachments, reads saved attachments
(.xls file), copies values from attachments to text file and copies text file
to FTP server. The app is scheduled to run at 7pm everyday.

It works fine on my development machine. But when I install and run it from
production server it generates the following error:

“COM object with CLSID {00024500-0000-0000-C000-000000000046} is either not
valid or not registered.”

This exception is thrown, when it tries to read values from excel file.
Production server is Windows 2003 Server. I believe this is because MS Excel
is not installed on the production server. How can I fix this? Is there any
way without installing MS Excel on production server?

Thanks
