We are trying to run the Arc Hydro Tools - Tutorial 2.0 (published by ESRI) with the dataset from the HUC8 Dataset - San Marcos River. We are trying just the 1st step (Level DEM) and we get the following error. We are just beginners, so we don't know if we missed something or there is an installation / config problem. Please find attached the screenshot with the error.
Thanks for clearing the matter.
