Question

Answer 1

Add a reference to the Microsoft.Office.Interop.Excel assembly.

• Right click on your project
• click add reference
• find the reference in the built-in references list

Answer 2

Sounds like you're missing the Primary Interop Assemblies. PIA's get installed with Office if you choose a Complete installation or specify them during the installation process. You can also download the PIA's you need from Microsoft.
