Hey,
I have thought of updating the HEC HMS 4.7.1 to HEC HMS 4.9 and after uninstalling hec hms 4.7.1 and Installing 4.9 version, started working on 4.9 version but it does not upload Terrain file, and secondly the HEC HMS 4.9 is working under open binary jdk and it is not working. as i have uploaded the screen shots of both in the scenarios.
Kindly have a look at it.
A kind request to Team HMS to kindly resolve this issue.
Thanks
