Cannot start program because opencv_core248d.dll is missing

edit

Hello,

I'm trying to install OpenCV. Turns out this is far more complicated as expected. The tutorials are all outdated. Here is my current problem:

I'm running on a 64 bit machine, and am trying just a simple sample code:

#include <opencv\cv.h>
#include <opencv\highgui.h>

using namespace cv;


int main() {
    Mat image;

    VideoCapture cap;
    cap.open(0);

    namedWindow("window",1);

    while(true) {

        cap >> image;

        imshow("window", image);

        waitKey(33);
    }


    return 0;
}

When I run this, I get an error stating that opencv_core248d.dll is missing. Checking the bin directory, it is there. How do I fix this?

Regards
