When i tried to install arc hydro on windows 8 in Arcgis 10.1, i got following error
“Erro 1723. There is a problem with this windows installer package. A DLL required for this install to complete could not be run. contact your support personnel or package vendor. Action ISSetupFIlesExtract, entry : SFStartupEx, library: …\…”
I have tried Arc Hyro 2.0 also but it gives the same error and similar things happen when i try to run arc SWAT.
Please Help
Windows Log information shows
“Error 2732. Directory Manager not initialized”
We have not yet tested with Windows 8. Please check back for updates. In the meantime, the Arc Hydro tools work with Windows 7.
Error DEM reconditioning is still present in BETA,
Error executing PolylineToRaster function in which FID for NHDFlowline is still taken from C:\Users\Username\AppData\Local\Temp\arcDBFD\AH20130130104314\tmp5171 which results in a “Error HRESULT E_FAIL has been returned from a call to a COM component”.
TargetLocations and Workspace are setted correctly. Standalone PolylineToRaster function works properly and takes FID from the Workspace folder. Tryed with ObjectID field in NHDFlowline.
Win7x64, AG 10.1 SP1, latest version of ArcHydro from https://mft.esri.com
Any info will be helpful.
When I tried to install arc hydro on windows 7 in Arcgis 10.1, I got an error stating “PSConfig Patch failed”.
Any help would be appreciated.
I keep getting “tool not valid” on all the archydro tools. How do I make them valid?
It looks like the toolbox in the map is out of sync with the registered files.
Steps1: make sure arc hydro is installed (check in C:\Program Files (x86)\ESRI\WaterUtils\ArcHydro\bin and make sure you have dlls)
Steps2: If it installed, try to open a new map (may need to delete the normal.mxt).
If you still have he problem you may need to reinstall Arc Hydro.

I just (successfully) installed Archydro for 10.1. In this version I can’t find a few functions I used earlier, like Flow direction with sinks (Terrain preprocessing). Is this one not necessary now, or how do I take sinks into account when calculating flow directions? The new functions for flow direction within sinks/streams/lakes does not help me, as far as I understand.
What should I use to allow for flow direction calculations to take sinks into account?
This tool is still available in the toolbox.
However we have modified the “standard workflow” so that the flow direction grid gets created first and then gets adjusted for streams/sinks/lakes.
The sink structures required by the Adjust Flow Direction in Sinks tool are now created by the tool Create Sink Structures using either known sink polygons/points or sink polygons generated by the sink evaluation tool if the location of the sink polygons is unknown.

I am looking for the latest documentation available and found this post that explains how to get to the new FTP site.

I have not been successful in using the login/password provided there.
Can someone tell me how and where to get the documentation?
