From a Visual Studio command prompt (elevated to administrator if you are on Vista) you can type in the following... gacutil /i \Microsoft.Office.Interop.Outlook.dll The will be "C:\Program Files\Microsoft Visual Studio 9.0\Visual Studio Tools For Office\PIA\Office12" if you have Visual Studio 2008 installed on your C: drive. For other versions just do a search on your hard drive(s) for this file and register it. Voila!
