I've upgraded to ArcGis 10.5 and have tried to install the relevant ArcHydro version (obtained from /archydro/archydro/Setup/10.5/), but the installation won't progress beyond the 'PreInstall' stage. The message that pops up says 'The ApFramework could not find the Arcgis 10.3 for Desktop install directory C:\ ARCGISHOME\'. Can anyone assist?
I'm having the exact same issue. Have you been able to find a solution as of yet? I've also tried the 32 and 64 bit versions, no luck.
Sadly I haven't found a solution for this problem yet. My local ESRI support team have apparently sent a query through to the technical guys at ESRI in the US but there's been no response.
This situation is extremely frustrating!!
Kerry- our IT folks were able to get it installed. It had be done as user 'Admin' with full privileges. IIRC the previous versions did not require this. Try that!
Brilliant! That worked perfectly.
Many thanks Royce - much appreciated!
