I‘m running Python 2.7 on Windows 7 64-bit, and when I run the installer for setuptools it tells me that Python 2.7 is not installed. The specific error message is:
`Python Version 2.7 required which was not found in the registry`
My installed version of Python is:
`Python 2.7 (r27:82525, Jul 4 2010, 07:43:08) [MSC v.1500 64 bit (AMD64)] on win32`
I‘m looking at the setuptools site and it doesn‘t mention any installers for 64-bit Windows. Have I missed something or do I have to install this from source?
Apparently (having faced related 64- and 32-bit issues on OS X) there is a bug in the Windows installer. I stumbled across this workaround, which might help - basically, you create your own registry value HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore\2.6\InstallPath and copy over the InstallPath value from HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\InstallPath. See the answer below for more details.
If you do this, beware that setuptools may only install 32-bit libraries.
NOTE: the responses below offer more detail, so please read them too.

最后找到一个64为的PIL，安装之后OK
