Your project is Win32 bit but you link it to 64 bit version of OpenCV. Solutions:

  1. Link your project to 32 bit version of OpenCV.
  2. Or change your project's settings to 64 bit, see this link for more details.

In the fifth step 5.In the Type or select the new platform drop-down list, select a 64-bit platform. the dropdown menu is empty.

It is possible that your machine is installed by a Windows 32 bit version, that makes VS installs its 32 bit version too. Hence, you did not find the "New" option and selected the 64 bit project.

I'm not using windows or visual studio, but it looks exactly like your problem.
