I was trying to install OpenCV+Python in my windows7 34bit PC. Downloaded opencv-3.1.0 + python-3.5.1 + numpy-1.10.4not able to complete and work on it. Googled a lot searched and some idea said that use lower version then downloaded OpenCV-2.2.0-win + python-2.7.11 + numpy-1.9.1-win32-superpack-python2.7 Still not able to complete
