Hi. I am running Windows 7 on an HP computer.
I downloaded: http://mirror.lagoon.nc/pub/gnu/emacs/windows/emacs-25.3-i686.zip It unzipped fine and I have a folder `bin' (among other folders) with file `runemacs.exe'. Double-clicking `runemacs.exe' successfully launches the GUI for Emacs. I can choose `Tool' and `Compare(Ediff)' and it seems to work fine for comparing directories, but, if I try and compare files, I get the error: `No such file or directory, diff' Is this a bug or is it to be expected (given that I am running Windows 7 and the only gnu-related thing I have on my computer is the unzip of `emacs-25.3-i686.zip')? I hope someone can clarify this as I am quite confused. Sincerely, David Wardle Auckland NEW ZEALAND.
