I am running into an error message while running Sink Prescreening with a minimum drainage area set to something other than 0:
"Error HRESULT E_FAIL has been returned from a call to a COM component"
If I leave the minimum drainage area = 0 then it works just fine. I ran through the usual delete temp folder items, start from a fresh .mxd, and check ApUtilities paths. I am using Version 2 in Arc10 on Windows 7 64-bit.
Anyone have any thoughts on how to avoid this error?
