There error info is same as Issue7511 .
Here is info about my machine:
OS: Windows Server 2008 R2(64bit)
I have installed both VS2010 and VS2008 in my machine.But VS2010 intalled before VS2008.
Also. I can found vcvars64.bat at dir:C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\amd64, but i don't know why Python can't found it.
There is a temporarily way to avoid the error ,we can manual execute vcvars64.bat before intall python module, But I think it's a python bug.

> There error info is same as Issue7511.
Yes. Issue 7511 will be fixed at some point in distutils2. Closing this
as a duplicate.
