• Download and extract CoCoA exactly in disk C:
  You should have:
  • the directory called exactly C:\cocoa-5.4
  • with inside the directory emacs (among other things)
  Typical bad configuration: if it is called C:\cocoa-5.4blah, and it contains another directory called cocoa-5.4, it is NOT good.
• Download and extract Emacs where you want (but preferably somewhere on disk C:)
  We suggest ftp.gnu.org/gnu/emacs/windows/emacs-25/emacs-25.3_1-x86_64.zip (~100Mb).
• Now follow these steps for linking Emacs to CoCoA:
  • close Emacs (if open)
  • click on Control Panel
  • click on System and security (for some MSWindows versions)
  • click on System and then on the tab Advanced
  • click on Environment variables (it is the button at the bottom of the window)
  • click on new for System variable, or just edit the variable HOME if you had already defined it for a previous version of cocoa-5.x) and then set exactly:

    variable	HOME
    value	C:\cocoa-5.4\emacs

  • click on a few OK to close all the windows
ALL DONE!! info & screenshots

In some versions of windows there is an error if you start CoCoA from a file "myfile.cocoa5" which is not on disk "C:"

Setting up Emacs for Emacs experts:
If you have already defined your own favourite Emacs options/colours/.. you might prefer to pick and copy from cocoa-5.x/emacs/cocoa.emacs into your .emacs only the settings you desire.
