Can't get NetworkAnalystExtension

I need to get a hold of NetworkAnalystExtension but for some reason FindExtension always returns null.

                IExtensionManager extMgr = GetExtensionManager(); //note: extMgr is returned OK
                UID uid = new UIDClass();
                uid.Value = "esriNetworkAnalystUI.NetworkAnalystExtension";
                IExtension ext = extMgr.FindExtension(uid);

I also tried using the GUID in uid.Value but got the same null return.

Also tried using IApplication, but again it just returns null.

Any ideas? Thanks.

Have you tried to display all loaded extensions with a for-loop and IExtensionManager.Extension[index]? If it's not there either, it's probably not loaded...

I put the loop in and did get "Utility Network Analyst".

Any other ideas? Thanks.

Have you tried something like

IExtension analystExtension = pIApplication.FindExtensionByName("Utility Network Analyst");

That did it. Still don't understand why the other techniques don't work.

Thanks.
