Whenever I try any of these tools " Drainage line processing and catchment polygon processing" it gives me this error
"error hresult e_fail has been returned from a call to a com component"
I tried it with different target locations -local and network, tried it through gdb and mdb gedatabases .
I found no solution so far......It works ok with archydro 10.0 but not with 10.1 or 10.2.
Help, Pleeeeeeeease.
