I am working on Windows Professional 7 on a 64-bit computer with Processors Intel (R) Xeon( R) CPU and have problem with ArcHydro. It can not perform the operation "Sink Selection". Does ArcHydro in general has problems with 64-bit and how can I solve them? Does the model only capcable of debugging for Intel32?

The error message is:
System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.
   at ESRI.ArcGIS.Geoprocessing.GeoProcessorClass.Execute(String Name, IVariantArray ipValues, ITrackCancel pTrackCancel)
   at ESRI.APWR.ApHydro.ArcHydroOp.SinkSelection(ApLayers apLayers, Boolean overwrite, Int32 debug, Double depthMin, Double areaMin, Double volumeMin, Double drainAreaMin, ITrackCancel& trackcancel, IGPMessages& messages, String& exMessage) in C:\Projects\10_Final\ArcHydroTools\src\ApHydro\ArcHydroOp.vb:line 6955
Failed to execute (Sink Selection).

Thanks a lot!
