OS is Windows 7 x64, python using 2.6.2 amd64, SDK installed, but when I
build some module by setup.py, it always traceback ValueError.

ValueError: [u'path']

I printed out the variables "result", it only had key 'path'.

Do you have VS2008 installed also?

yes, I have already installed VS 2008 (but it is Express Edition for VC,
VB ,C#...I have no money to buy standard edition.)

So when you run vcvarsall.bat, and then do "set", does it print any of
the variables "include", "lib", "libpath", "path"?
