I have installed OpenCV 2.4.2 and Visual C++ 2010 - (Windows 7, 64 bit). While executing a sample program, I have got an error as follows:

The program can't start because opencv_core242d.dll is missing from your computer. Try re installing the program to fix this problem.

That dll file was already present in the folder. But I tried re-intsalling and still I am getting the same error.

If possible, someone can please help me to solve this error.

I believe the problem is your paths.

What is your "Include Directories"?

What did you type in in "Additional Dependencies"?

it's the binaries(dlls), that can't be found, so you have to adjust your PATH environment variable.

  • if you built those locally, you have to add 2 items, the path to the debug and the release folder (separated by ; ). , that should be similar to :


  • if you're using the prebuilt libs, then only one:

    E:\code\opencv242\build\x86\vc9\bin // whatever os / vs version you're using

Make sure that the location of the DLL (the directory) appears in the environment variable PATH.
