VSTO August CTP COM Exception

Question

I wrote an application that traverses the contact folders and the contacts within Outlook using the BETA 2 bits. I moved to the August CTP and everything works except for the COM reference to the Outlook 11.0 library. Everytime I enter the section of code (see below) below I get a nasty COM error message. I traced the CLSID to the Outlook 11.0 library however I can't find a way to fix the problem. I tried reinstalling the Outlook 2003 PIA and reinstalled the VSTO 2005 bits with no luck.

Windows XP SP2 / Outlook 2003 / VS 2005 August CTP / VSTO 2005 August CTP

ERROR:

System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80040154.

CODE:

try

{

Outlook.Application app = new Outlook.Application();
Outlook.NameSpace ns = app.GetNamespace("MAPI");

etc...

}


HELP!!

It is not possible to use Office.Interop code without having a licensed version of Office installed on the target machine.
