Hello,
There is no version of SALOME-HYDRO for Windows, and as SALOME-HYDRO is no longer maintained, there won't be one. However, most of SALOME-HYDRO's pre-processing features are now integrated into Q4TS, which is much more intuitive to use, see here:
gitlab.pam-retd.fr/otm/q4ts. It does, however, require QGIS, TELEMAC and SALOME (standard version) to be installed. SALOME can be downloaded here:
www.salome-platform.org, while you will need to compile TELEMAC on Windows for now, using the wintel repository:
gitlab.pam-retd.fr/otm/wintel.
