No importlib in Python 3 64 bit ?

[Andrej Viktorovich]

Hello,

I have 32Bit and 64Bit installations on my Windows 10 machine. I do import importlib in both of them. 

32bit works fine while 64bit prints error:

>>> import importlib
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\me\AppData\Local\Programs\Python\Python36-32\Lib\importlib\__init__.py", line 57, in <module>
    import types
  File "C:\Users\me\AppData\Local\Programs\Python\Python36-32\Lib\types.py", line 171, in <module>
    import functools as _functools
  File "C:\Users\me\AppData\Local\Programs\Python\Python36-32\Lib\functools.py", line 23, in <module>
    from weakref import WeakKeyDictionary
  File "C:\Users\me\AppData\Local\Programs\Python\Python36-32\Lib\weakref.py", line 12, in <module>
    from _weakref import (
ImportError: cannot import name '_remove_dead_weakref'


Why and how to solve this problem?
