I had developed a system that deals with excel sheets in 2006 using MS VS 2005. Now, I can not use the same reference with MS VS 2012.

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. Imacs user guide.
VS 2008 / 2010:

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:

If you have VS 2013 Express and you cant find Microsoft.Office namespace, try this ('Microsoft Excel 12.0 Object Library' if you want to use Office 2007)

Building off of Mulfix's answer, if you have Visual Studio Community 2015, try Add Reference.. -> COM -> Type Libraries -> 'Microsoft Excel 15.0 Object Library'.

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.

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.

Hello
My os is W7 famillial (64 bits)
I use office 2010, and visual studio 2010 express C#
I wanted to learn to make excel file, and fill it as I want using C# program
In visual studio.
I still get an error on the .excel on the two linesjust below
using Microsoft.Office.Interop.excel;
using Excel = Microsoft.Office.Interop.excel;
despite I did what I describebelow
Ihave first downloaded on this site PIARedist.exe
when I click on it, it has unzipped 3 files o2010pia_eula.txt, O2010pia.msi,o2010pia_readme.rtf
I did open a command dos, went to the dir which contains O2010pia.msi
Microsoft.office.interop.excel.dll Path
I did executemsiexec.exe /I O2010pia.msi
And re-add referenceMicrosoft Excel 14.0 Object Library
·1.On the Project menu, click Add Reference.
2.On the COM tab, locate Microsoft Excel Object Library, and then click Select. In Visual Studio 2005, locate Microsoft Excel 11.0 Object Library on the COM tab.
But I was not prompted to “generate wrappers” ( I don’t know what does it means !) like in the third step (below)
3.Click OK in the Add References dialog box to accept your selections. If you are prompted to generate wrappers for the libraries that you selected, click “Yes”.
