I'm working on a class project. The instructor gave us the hydrologic 
extension from ESRI. I can't get it to work

Here is the instructions I got:

Goto the tools menu click on customize and then click on the options tab

click on the add from file button and path to the esrihydrology_v2.dll in 
the extension folder

click on the toolbars tab and place a check the box next to Hydrology 
Modeling and close the dialog box

What I am getting is when I select the esrihydrology_v2.dll "no new objects 
added"

Any ideas?
