Don't use the mklink. Use the CTRL + F in Notepad ++ and use Find and Replace.
Take your time and it's pretty easy.
My personal mistake was extracting the archive to Skyrim but it extracted to . . .\Skryim\Skyrim.
Took me forever to realize that. After messing the the ModOrganizer.ini and moved all the files out of . . .\Skyrim\Skyrim to just . . .\Skyrim it all started working.
If you're still having issues. I'm on discord and you can do a sharescreen while I try to help you out.
Let me know.
