I am getting the following error on my workstation when I am trying to work with a COM object.

An unhandled exception of type
‘System.Runtime.InteropServices.COMException’
occurred in CarteGraphInterface.exe

Additional information: Retrieving the
COM class factory for component with
CLSID
{3963F0F8-6B0C-4A65-90F4-F60168044014}
failed due to the following error:
80040154.

I have read through a few questions here on SO and non of them have helped. That ID is not listed anywhere in the registry. Does it need to be added?

Update: A bit more information. When I choose “Add Reference…” in VS2008, the object is listed there (that is how I found it initially), and the source is listed as a *.exe. regsrv32 didn’t work.

    None of these solutions worked. I assume that they do not actually have APIs that could be used with .NET (if at all).
