001324: Personal geodatabases are not supported in 64-bit versions of ArcGIS.


Personal geodatabases do not scale well in the 64-bit environment. They cannot be used by 64-bit versions of ArcGIS.


Modify your data sources to a supported type with 64-bit ArcGIS. Using the Create File GDB tool, you can create a file geodatabase and import your layers into it using the Feature Class to Geodatabase (multiple) tool.
