Appreciate the links, abbodi1406. The first one is 11.0.20 as I already tried that. The last one is an .msu file which will not work without IE 11.0.17 or below installed first AFAIK. As for the .cab files, have not tried them yet, but can probably use the files inside to replace 11.0.20. I'm still not sure where to put all the files anyways.
Which Internet Explorer folder? The one in Program Files(x86) or Program Files? Yes, i'm using Windows 7 x64 so IE is x64 also. Are you sure no need to replace files or folders elsewhere, i.e. in /Windows/System32?
