Hi, I have successfully installed python. And pyserial, inputs(xbox), numpy as well in CMD window. I also successfully installed opencv-python in CMD window.I copied the python -- 'cv2.pyd' file to 'site-packages' folder.But right now the problem is when I open the 'Sentry Project.exe' file then the pop-up window shows ERROR: APP can not start normally (0xc000007b)... :(I search on web it seems miss the .DLL files. But I am sure the 4 DLL files(cv210.dll, cvaux210.dll, cxcore210.dll and highgui.dll ) are already in 'SysWOW64' folder.Anyone met the same thing to me? Can anyone share any comment for this issue?
