I have Emacs 24 and MikTeX on Windows 7 professional and I have recently installed AUCTeX 11.86 from package-install.
The installation seems to have completed successfully, I even succeeded at compiling a latex sample file, but I can use AUCTeX only in the emacs instance where I issued the installation command, where it gets loaded by package-install. I can't do the same with a new emacs instance.
Nothing seems to have been written in my .emacs file upon installation and I can't find the
auctex.el file, which the AUCTeX installations instructions report to be found inside the auctex directory
(.emacs.d/elpa/auctex), to load AUCTeX at initialization time.
Any idea on how I can solve the issue?
