hi -

I'm trying this :

 Type t = Type.GetTypeFromProgID("esriArcMapUI.MxDocument");
            IDocument mxd = Activator.CreateInstance(t) as IDocument;

and I've tried

 IDocument mxd = New MxDocument()

neither work.  I get

Retrieving the COM class factory for component with CLSID {006B1AFE-C66C-11D0-B94C-080009EE4E51} failed due to the following error: 80040111.

I've looked through the help and can't find anything that is pertinent to this issue. Any help would be appreciated.
