.NET 3.5 ActiveX dll InteropServices.COMException

Using vs2008 .NET 3.5 SP1 I am trying to use an ActiveX dll in my c# console application project and I am getting this runtime exception: ``` System.Runtime.InteropServices.COMException (0x800702E4): Retrieving the COM class factory for component with CLSID {4E58088E-7275-4EAA-8958-A9CCC971DDE9} failed due to the following error: 800702e4. ``` How do I go about finding out a solution to this issue? I have used regasm.exe to register to DLL previously and it registered successfully. name of DLL is `interop.sterling.dll` simple code: ``` using SterlingLib; public class OrderPlacer { private void SendOrder() { var order = new SterlingLib.STIOrder(); } } ``` I added the reference to this DLL by browsing to it and adding it as a reference - then placing in the `/bin/debug` folder using reflection: ``` SterlingLib.STIOrderClass is a class whose base class is System.__ComObject It implements the following interfaces SterlingLib.ISTIOrder SterlingLib.STIOrder SterlingLib.STIOrder is an interface ``` I am running Vista so I think this may be a UAC issue not allowing full rights unlike it would if I was running XP.
