The following is a known issue with HEC-GeoRAS 10.0.

Issue #1
Applies To: Version 10.0

Problem: The HEC-GeoRAS toolbar has buttons with the text "Missing" on them and none of them work.



Solution:
On machines that previously had ArcGIS 9.3 and HEC-GeoRAS 4.3 installed, the uninstall process for HEC-GeoRAS 4.3 did not properly cleanup certain keys in the registry. This causes the GeoRAS 10 installation package to bypass one of the pre-requisite install packages and cause the error.

To solve this problem do the following:

1. Uninstall HEC-GeoRAS Version 10.0.
2. Using the registry editor (regedit.exe), delete the following keys if they exist...
   • HKEY_LOCAL_MACHINE\SOFTWARE\ESRI\Applications\WaterUtilities\
   • HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ESRI\Applications\WaterUtilities\
3. Delete the following folders if they exist...
   • C:\Program Files\ESRI\WaterUtils\ApFramework9
   • C:\Program Files (x86)\ESRI\WaterUtils\ApFramework9
4. Now reinstall HEC-GeoRAS 10.

The HEC-GeoRAS toolbar should now be fully functional.

The following is a known issue with HEC-GeoRAS 4.3.

Issue #1
Applies To: Version 4.3

Problem:

Solution:
Install the updated HEC-GeoRAS 4.3 (March 2012) setup package.
