I get the following error when installing Arc hydro (ArcHydroTools_2_0.msi)
"Setup has not detected the ArcGIS Desktop product installed on the system ..."
Or if I have ArcMap running it says I can't install while ArcMap is running.
I am using a 180-day trial of ArcGIS 10.1 for desktop that came with a textbook, does that matter?
