py2exe > BeginUpdateResource: Access is denied.

[dusca]

Estou tentando criar um executável com o py2exe mas tenho este erro:

Traceback (most recent call last):
  File "setup.py", line 74, in <module>
    windows = [targetForm]
  File "C:\Python27\lib\distutils\core.py", line 151, in setup

    ensure_unicode(python_dll).upper(), 1, False)
RuntimeError: BeginUpdateResource: Access is denied.
