Can't reload :Program FilesMATLA​BR2018bbin​win64ocv.d​ll'

I get the error "Can't reload :Program FilesMATLABR2018bbinwin64ocv.dll'" when running the "Face Detection and Tracking Using the KLT Algorithm" from https://www.mathworks.com/help/vision/examples/face-detection-and-tracking-using-the-klt-algorithm.html#d120e3968

I clicked the link try it on Matlab and then run the script. I restarted computer but the error does not disappear.

Complete error description is as follow:

Can't reload 'C:\Program Files\MATLAB\R2018b\bin\win64\ocv.dll'

Error in vision.CascadeObjectDetector (line 205)
                obj.pCascadeClassifier = vision.internal.CascadeClassifier;

Error in face_detection (line 2)
faceDetector = vision.CascadeObjectDetector();

Unfortunately we do not know what causes this yet. In some cases, it has been tracked down to needing to install MS Visual Studios Run Time Redistributable. I think it was the 2015 version that was mentioned, but if I understand correctly any version at least that new should provide the DLLs.

Thank you very much for your help. I installed MS Visual Studios Run Time Redistributable 2013 before and it didn't work. But with 2015 version, the problem has gone. Thanks again.
