You can also try installing it in Visual Studio via Package Manager.

Run Install-Package Microsoft.Office.Interop.Excel in the Package Console. This will automatically add it as a project reference.

Use is like this:

Using Excel=Microsoft.Office.Interop.Excel;

Instead of early binding the reference  there s an open source project called NetOffice that abstracts this from your project  making life much easier   That way you don t have to rely on your users having a specific version of Office installed   NetOffice Codeplex site

Use NuGet  VS 2013     The easiest way in any recent version of Visual Studio is to just use the NuGet package manager   Even VS2013  with the NuGet Package Manager for Visual Studio 2013 extension    Right-click on  References  and choose  Manage NuGet Packages      then just search for Excel       VS 2012   Older versions of VS didn t have access to NuGet    Right-click on  References  and select  Add Reference   Select  Extensions  on the left  Look for Microsoft Office Interop Excel  Note that you can just type  excel  into the search box in the upper-right corner         VS 2008   2010    Right-click on  References  and select  Add Reference   Select the   NET  tab  Look for Microsoft Office Interop Excel

You have to check which version of Excel you are targeting   If you are targeting Excel 2010 use version 14  as per Grant s screenshot answer   Excel 2007 use version 12   You can not support Excel 2003 using vS2012 as they do not have the correct Interop dll installed
