HRESULT: 0x80040228

When run the arcgis engine codes in the console application, may come to the exception: HRESULT: 0x80040228.

Then can use these code to enable the lisence:

ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.EngineOrDesktop);
ESRI.ArcGIS.esriSystem.IAoInitialize ao = new ESRI.ArcGIS.esriSystem.AoInitialize();
ao.Initialize(ESRI.ArcGIS.esriSystem.esriLicenseProductCode.esriLicenseProductCodeEngine);
