Hey guys, I just looked this up to take ownership of my files. https://www.windowscentral.com/how-take-ownership-files-and-folders-windows-10 .Following these instructions I went in and gave full controll to my primary profile for the entire pso2_bin. this is after 3 installs and hours of searching. My exact error was similar to this person post https://forum.pso2.com/topic/2941/the-file-cannot-be-accessed-by-the-system. I truely hopes this helps everyone else whos been waiting for 7 years. Also devs and mods please bump this up if it helps
