Dean D., et. all
Has anyone worked out the command line, or MSI installer edits in Orca, needed to install ArcHydro (or HEC-GeoHMS) when Python26 is installed to a location other than ESRI's C:\Python26\ArcGIS10.0 location?
I have an existing Python26 installation to the Python.org default C:\Python26 location, and ArcHydro installer is throwing ERROR 1606. Could not access network location ArcGIS10.0. Also seeing a related installer issue that, lacking the Python26 default location, if a large data drive (D:\) is present--the installer defaults to a TARGETDIR of D:\
Looking through the .msi installer the ESRI default location looks to be hardcoded in:
[INDENT]CustomAction --> SetPythonHome: Source PYTHONHOME: [PYTHONDIR]ArcGIS10.0
(which is the default ArcGIS Desktop10.0 Python install location ESRI uses)[/INDENT]
For the Desktop10.0 install we can use the INSTALLDIR1= command line value to specify the Python26 install location. But I can't figure a similar configuration out for the ArcHydro package install.
Ideas?
