The reason the COM failure shows up is because Office is not installed.

But, you cannot use Office Interop in a web application. It will work on your dev machine, but once you upload the web application to a host and multiple uses start using, it will fail.

You need to use a library that does not depend on Office being installed to retrieve the data. If the data in the Excel sheet is in tabular format, you use OleDb (database) methods to get the data, treating your Excel sheet as a rudimentary database table.

If the data is in specific cells, you would need to use something like the OpenXML SDK to get at the data in the cells.
