I had issue installing OpenCV libraries because I did not have a system path. May I know how to finalise the installation so that I can program object detection in visual studio?

Now I can understand your question. what do you mean "I did not have a system path. "? how did you install opencv?

I did installation using pre-built libraries. I have downloaded OpenCV 3.4.3 but I could not finalize installation by setting environment variable. When I typed "setx -m OPENCV_DIR D:\OpenCV\Build\x64\vc14" in command window, it said access to the path registry is denied. Plus I went to Control Panel > System Security > System > Advanced System Settings > Environment Variables > System variable however I could not find path in system variables. So may I know what to do about it?

I don't understand "I could not find path in system variables" : you should find it

I still can't find it. I have sent OpenCV admin the video via email. You'll get what I mean. In addition, I could not upload attachment in this forum.

These are the variables I have found under system variables of the environment variables

  • ComSpec(%SystemRoot%\system32\cmd.exe)
  • DriverData(C:\Windows\System32\Drivers\DriverData)
  • KICAD_PTEMPLATES(C:\Program Files (x86)\KiCad\share\kicad\template)
  • MEmu_Path(C:\Program Files (x86)\Microvirt)
  • PATHEXT(.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC)
  • PSModulePath - (%ProgramFiles%\WindowsPowerShell\Modules) - (%SystemRoot%\system32\WindowsPowerShell\v1.0\Modules)
