how to install paramiko correctly?

[sir]

My system:win7+python3.4 .
I have installed Crypto and Paramiko .

     C:\Windows\system32>pip3.4  install  Crypto
     Requirement already satisfied (use --upgrade to upgrade): Crypto in 
d:\python34\
lib\site-packages
     Cleaning up...

     C:\Windows\system32>pip3.4  install  Paramiko
     Requirement already satisfied (use --upgrade to upgrade): Paramiko 
in d:\python3
4\lib\site-packages
     Cleaning up...

when import paramiko :


     >>> import paramiko
       Traceback (most recent call last):
       File "<stdin>", line 1, in <module>
       File "D:\Python34\lib\site-packages\paramiko\__init__.py", line 
30, in <module
       from paramiko.transport import SecurityOptions, Transport
       File "D:\Python34\lib\site-packages\paramiko\transport.py", line 
49, in <module>
      from paramiko.dsskey import DSSKey
      File "D:\Python34\lib\site-packages\paramiko\dsskey.py", line 26, 
in <module>
      from Crypto.PublicKey import DSA
      ImportError: No module named 'Crypto'

When i change the F:\Python34\Lib\site-packages\crypto  into 
F:\Python34\Lib\site-packages\Crypto ,

     import paramiko
     Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
       File

_.py", line 31, in <module>
       File

"F:\Python34\lib\site-packages\paramiko-1.13.0-py3.4.egg\paramiko\comm
py", line 129, in <module>
     ImportError: cannot import name 'Random'
