Helllo,  
I tried to use different version of opencv, with different version of Visual studio, on Windows 10.  
I always get the same error when I run my code, during compilation there are no errors, but when I run my code I always get (impossible to run the code because opencv\_world320d.dll is not found) currently VS2017, opencv 3.2.  
everything is configured normally in C/C++, and in the linker

Thank you for your help

make sure those DLLs can be found. that means the containing directory has to be in the PATH environment variable.

additional recommendation: you should use a newer version of OpenCV (because v3.2.0 wasn’t compiled for Visual Studio 2017), or you should build that ancient v3.2.0 version yourself.
