Hi, I have downloaded the arcgis version 10.4 and I need the Archydro tool to work on it. Does anyone knows if there is a version of archydro for arcgis 10.4? Or do i need to download other version of Arcgis? I thought wierd because I got Arcgis from free trial on esri and they gave me version 10.4 and for other friends who did de same, other versions. Thank you!
