How to install Excel Services on Sharepoint 2010 Enterprise Client Access License?

I have a farm installation of Sharepoint 2010 Server with Enterprise Client Access License. I want to publish an excel workbook to a document library on my site, but I am unable to do so. When I go to Central Admin -> Manage Service Applications, I do not see a service application for Exce开发者_高级运维l Services and its not available under the New menu there either. Kindly let me know how to install Excel Services on my Server.

Make sure you have SharePoint 2010 Server and not SharePoint 2010 Foundation.
