Em đang học và làm theo Khóa học lập trình ADB Auto Android[bài 3]

lỗi sinh ra ở phần code:

var accPoint = KAutoHelper.ImageScanOpenCV.FindOutPoint(screen, ACCOUNT_BMP);

Could not load file or assembly 'Emgu.CV.World, Version=4.1.1.3497, Culture=neutral, PublicKeyToken=7281126722ab4438' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Warning There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "KAutoHelper", "x86".

Mong mọi người giúp ạ.
Em cảm ơn.
