I was trying to create a windows forms using the Microsoft.Office.Interop libraries, but I cannot find them. I tried to follow the guides only and installed the Microsoft Office 2010: Primary Interop Assemblies Redistributable, but the references did not show up in the COM tab. I closed VS.NET, restarted my computer and they still did not show.
I am using Visual Studio 2010 with .NET Framework 4.0.3.
PIA is just an interop layer, you need Office installed to see a COM reference. If you reference a COM type library, AND a corresponding PIA is installed correctly, your reference will be replaced by a PIA one. You can also reference the PIA directly by browsing to its folder and add reference, but the PIA won’t be functional unless you have Office installed.
