Hi, I try to run OpenCV on my computer (Windows 7, Visual Studio 2013 Express). I have followed instructions in tutorials:

I added path to include folder in “Additional Include Directories” and to libraries in the linker options. Example project can be built, but after start I get an error:

The program can't start because opencv_world300d.dll is missing from your computer. Try reinstalling the program to fix this problem.

Mentioned library is in OpenCV bin folder. I tried to add location of that folder to PATH variable and copied file to Debug folder of project but nothing has changed. Help will be really appreciated.

You have to put the opencv_world300d.dll into the folder where your .exe file is build.

The same for your release build but with opencv_world300.dll.

I have the same problem and I copied opencv_world300d.dll into the folder where .exe file exists, but the problem still exists! I am using Windows 10, VS 2015 and openCV 3.1. Can anyone help?

it worked if copy the opencv_world300d.dll and opencv_world300.dll to the same directory as the source file when you run your program via VS. if you want to run the .exe directly by double click it, then the dlls should be in the same place as the ,exe. But waht I wonder is, why add the path of the dlls to the PATH, doesn't work?
