Hello Millicent,
I have split this query into a separate thread.
See this article for downloading and installing all OpenFlows products: Downloading OpenFlows | Hydraulics and Hydrology Software
Also, see this informative article about what's new in the latest release of HAMMER: What's New in HAMMER CONNECT Edition Update 3 (version 10.03.05.XX)
Hope this helps.
Regards,
Yashodhan Joshi
Thanks a lot, Yashodhan
