Alright, I have tried a bunch of times the 
python setup.py install
command from my command prompt, and this is what I'm getting:
SCREEN
And when trying this:
from SimPy.Simulation import *
on Idle, I get this:
Traceback (most recent call last):
  File "C:/Python30/pruebas/prueba1", line 1, in <module>
    from SimPy.Simulation import *
  File "C:\Python30\SimPy\Simulation.py", line 320
    print 'SimPy.Simulation %s' %__version__,
                              ^
