I've been using an older version of emacs for some time now (under
Windows XP), and I have used auctex (MikTeX) without much trouble.
However, I noticed that there is a preview-latex system now
available. So, I downloaded the pre-compiled version of Emacs + AucTeX
emacs+auctex-w32-2006-05-14.zip
from the website
http://www.gnu.org/software/auctex/download-for-windows.html.
After unpacking and overwriting my old emacs files, I tried to run it,
but when the emacs window came up, there was an error message
Error (initialization): User has no home directory
Can someone help me find a way to set this (and possibly other
required) environment variables so I can avoid the error message? As
a kludge, I inserted this line at the top of my .emacs file
(setenv "HOME" "C:/")
but of course the error comes up anyway, since it's generated before
the .emacs file is read.
Furthermore, the README file for this distribution refers to an
INSTALL file, but there is none.
