I have Windows 8 operating system, Visual Studio 2013, I followed all steps to integrate opencv into visual studio. The following error appears: Error LNK1107: Invalid or Corrupt File, can't read at 0x2b8 (File opencv_calib3d248.dll) I checked identifying and integrating dll files, and I wrote all them in the linker !! Still the error appears, how can I solve the problem!
