I suggest modifying ‘run_salome.bat’ as shown below:

START cmd.exe /C %out_dir_Path%\W64\Python\python3.exe %out_dir_Path%\salome %* ^> log.salome_win.txt 2^>^&1
REM START %out_dir_Path%\W64\Python\python3.exe %out_dir_Path%\salome %*

This is very useful to catch an error while running a Salome script.
