Note:
This issue also occurs on other 64 bit windows OS(i.e. windows xp 64bit)

Load "testPy2.dll" needs vc++ runtime library (http://download.microsoft.com/download/2/d/6/2d61c766-107b-409d-8fba-c39e61ca08e8/vcredist_x64.exe)

Update "testPy2.dll", use this to reproduce the issue.
python code:
import sys
from ctypes import *

windll.LoadLibrary("testPy2.dll")
