I recently installed Visual Studio .NET. I am trying to automate MS Excel from Visual Basic .NET.

I have followed the steps listed in "HOWTO: Automate Microsoft Excel from Visual Basic .NE
Microsoft Knowledge Base Article - 301982€

I get the error "Namespace or type 'Interop' for the Imports 'Microsoft.Office.Interop' cannot be found.

What do I have to do to compile it successfully? Do I need to install the MS Office XP PIA first?
