pssnapin question and OneNote

hello,
I have been trying to get Brian Dewey's OneNote Provider to work (http://bdewey.com/2007/07/18/onenote-powershell-provider/). When I run the Enable-OneNote.ps1, I get a message that " No snap-ins have been registered for Windows PowerShell version 3.". The error message directs me to
Add-PSSnapin Microsoft.Office.OneNote. So now to my question, is the PSSnapin Microsoft.Office.OneNote a common snapin that should be available to me if I have OneNote installed? or should it be included in Brian's msi?

thanks

Joe
