I'm a fairly new user of the Arc Hydro tools, and I wanted to add the HEC-geoHMS tools to the Arc Hydro package. I downloaded the HECgeoHMS10.1.msi from the FTP site, but upon install, I get the error message: "An incorrect version of Arc Hydro Tools was found on the system. HEC-GeoHMS requires Arc Hydro Tools version 10.1.0.151." I had installed Arc Hydro this February, so I thought my version was fairly current. Even so, the only version of Arc Hydro I found on the FTP site was 10.1.0.157. My question is, will the HEC-geoHMS tools work with the Arc Hydro version 10.1.0.157? I'm hesitant to uninstall my current version of Arc Hydro if HEC-geoHMS will not work with the newest Arc Hydro version. If HEC-geoHMS does not work with the current Arc Hydro version, is there anything I can do to install the HeC-geoHMS tools with my version of Arc Hydro (current as of February 2013). Thank you very much for any response, Abby
For its configuration management practices HEC has Esri build the GeoHMS with a version controlled build of ArcHydro and bundles that version. But, those checks are only in the Windows Installer package for the HEC GeoHMS--not in its runtimes.
Meaning, you can safely uninstall the ArcHydro Tools from Add/Remove programs (i.e. appwiz.cpl), restart computer and then install the HEC GeoHMS package. It will detect no ArcHydro Tools present and as you found offer to install the requisite version as bundled in the .MSI package. Permit that to install, and to then complete the GeoHMS installation.
Then if you choose, you can immediately uninstall the bundled ArcHydro Tools, and download and install its most recent installer package from the sftp site. Just, while updating, don't try to run the GeoHMS toolbar without the ArcHydro Tools present.
Other than the Windows Installer packaging issues, the more recent developmental build of ArcHydro Tools should have no compatibility issues with the most recent build of HEC GeoHMS. But, if any issues are discovered they are likely to be bugs that the Esri Water Resources developers will need reported. Simply report all OS and ArcGIS program(s) configuration details when raising such an issue.
