Is there a version of ArcHydro for ArcGIS 10.1.3035? This is a version I got with the purchase of a book. The build numbers in the server all look like 10.1.0.xxx. I would really like to be able to use ArcHydro, so any help would be greatly appreciated...
For your version of ArcGIS v10.1 installer here
yellow.esri.com - /archydro/archydro/Setup/10.1/10.1.0.394/
If you use the background x64 processing, you can use the x64 version.
Pay attention, you need to apply all service packs and all patches to you arcgis v10.1 prior install this version of archydro.
Good luck
