“The application has failed to start because cxcore210.dll was not found”. Why would this happen?

Or else I came up with another solution just copy the dll files directly into C:\Windows\SysWOW64 folder (this is my system folder). This helped me and my code was executed.

Answer 2

The DLL needs to be somewhere in the DLL search path, otherwise the loader won't be able to find it.

The two easiest options are to copy the DLL(s) to the directory in which your executable is located or the directory from which you are running your executable, or to add the directory in which the DLL(s) are located to the PATH.

Answer 3

I had the same problem:

I configure correctly the properties of my project, like 100 tutorials says: But never work, so i try copy the dll to the application directory and works. I dont know why the linker dont see the dlls

I just copy the cv210.lib ,cvaux210.lib, cxcore210.lib ,highgui210.lib
