Create a new folder called "Emacs" on your C: Drive and extract emacs-24.5-bin-i686-mingw32.zip to it. No install necessary.
Type "%appdata%" in the windows explorer bar.
If there is an ".emacs.d" folder, delete it.
Extract the contents of the Scrivener Emacs config zip above to the ".emacs.d" folder in this folder. The folder location will be something like "C:\Users\bob\AppData\Roaming.emacs.d", where your name replaces bob.
Run Emacs with C:\Emacs\bin\Runemacs.exe. Create shortcuts as desired.
Delete ~/.emacs or ~/.emacs.d folders if they exist.
Extract the contents of the Scrivener Emacs config zip above to ~/.emacs.d
Run Emacs
Linux
Install Emacs 24.5 from your package manager
Delete ~/.emacs or ~/.emacs.d folders if they exist.
Extract the contents of the Scrivener emacs config zip above to ~/.emacs.d
Run Emacs
Note: Emacs 25 will also work and you’re welcome to use that version. I recommend Emacs 24.5 here because it is faster and we’re not using anything from Emacs 25.
