I have the above which I compile into an executable and run.

In some very rare instances, it is able to successfully return a value.

In almost all cases, I get the following exception:
{{{
Unhandled Exception: System.Runtime.InteropServices.COMException: Retrieving the COM class factory for component with CLSID {B1A7A4F2-47B9-4A1E-82B2-07CCD5323C3F} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)).
