[Bug]: ImportError: DLL load failed while importing cv2: The specified module could not be found.

Is there an existing issue for this?

[X] I have searched the existing issues and checked the recent builds/commits

What happened?

I've installed the webui having met the dependencies and followed the instructions precisely, and I get the error "ImportError: DLL load failed while importing cv2: The specified module could not be found." This error has plagued me since Monday night. This is my second PC. My main rig is comfortably running SD and has been since September of last year. I'm comfortable with the UI and the CLI. I do not know how to write code.

More context - I'm trying this on a fresh install of Windows 10 with all updates and dependencies. I've tried with a fresh install of windows and follwing all steps about 5 times, literally. Nothing about my approach is casual, I have tried and tried. Searching for this particular error has yielded virtually no solutions for me as the context has always been other software.

I've ONLY assumed that the WebUI might be at fault after exhausting my capabilities.

Steps to reproduce the problem

Go to .... https://github.com/AUTOMATIC1111/stable-diffusion-webui and follow the instructions for installing the webui on windows
run webui-user.bat
recieve error "ImportError: DLL load failed while importing cv2: The specified module could not be found."

What should have happened?

Well just as it should be and has in the past I should have had a complete installation at the end of the above procedure.

Additional information

I am using absolutely fresh windows installs fully updated all official Pro N. I have tried more times than is reasonable. I've tried more than one approach. I tried twice on Ubuntu and twice on Linux Mint and failed for other reasons - I am willing to do just about anything to get this working. Though I can't code I am also willing to search and read anything anyone shares with me. The machine in question was purpose built for SD from older equipment I have and a new MOBO and RAM. 32G RAM. i7 4790K.
