Error: The Microsoft Jet Database engine cannot find the input table or query 'GDB_GeomNetworks'
This error occurs when trying to import a coverage into the Montgomery GDB and the Water feature dataset using an ArcView license (Building a Geodatabase tutorial).
"The Microsoft Jet database engine cannot find the input table or query 'GDB_GeomNetworks.' Make sure that it exists and that the name is spelled correctly."
The feature dataset you are attempting to load data into is not considered a simple feature dataset. Additional licensing is required to load data into a personal geodatabase that is not simple. A simple feature dataset will contain either points, multipoints, polylines, or polygon features.
Solution or Workaround
Upgrade to either an ArcGIS ArcEditor or an ArcGIS ArcInfo license.
