(2) Download winmostar0_setup_X.X.X.exe from the Download page and run the installer. (X.X.X is the version number.)

(3) On 64-bit Windows, select either the 64-bit or 32-bit version. For most users, we recommend the 64-bit version.

(4) Select the installation destination (default: C:\winmos11) and start the installation.

If your security software blocks or flags the installer, please allow it to proceed.
You can overwrite an existing installation or choose a different folder to keep both versions.
When the installation finishes, Winmostar creates shortcuts in the Start menu and on the desktop.

(5) For a new installation, launch Winmostar and enter your license code in the dialog that appears at first startup.

(6) Install the necessary solvers for Windows (e.g., GAMESS, FDMNES). See the links below.

GAMESS
FDMNES
NOTE: NWChem, Quantum ESPRESSO, OpenMX, LAMMPS, GROMACS, Amber, and MODYLAS are included in the CygwinWM environment.

(7) Install the Cygwin environment for Winmostar.

(8) If necessary, configure your security software so that the Winmostar and Cygwin installation folders are excluded from real‑time scanning or blocking.

(9) To submit remote jobs, install the required solvers on the target Linux server. See the links below.

NWChem, Gromacs, Amber
If the server lacks a job scheduler (e.g., PBS/Torque), please install Slurm.
