In the ```exp_manager.py``` script, you need to change the line that reads

```rank_termination_signal: signal.Signals = signal.SIGKILL```

to...

```rank_termination_signal: signal.Signals = signal.SIGTERM if os.name == 'nt' else signal.SIGKILL```

That way it will work on Windows.

You're welcome.
