I'm unable to import tkinter in Python 3.5.0rc1.

The console says:

C:\Python35>python
Python 3.5.0rc1 (v3.5.0rc1:1a58b1227501, Aug 10 2015, 05:18:45) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import tkinter
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "C:\Python35\lib\tkinter\__init__.py", line 35, in <module>
     import _tkinter # If this fails your Python may not be configured for Tk
ImportError: DLL load failed: The specified module could not be found.


I'm on Windows 10 Home (64-bit).
