I am running GNU Emacs 24.3(freshly installed, with no additions or modifications) in windows 7 with MikTeX 2.9 (not ideal, but I can't change the operating system on this machine...)
It is easy to find AUCTeX under the package manager in Emacs, but once I installed it, opened a sample paper with my standard mess of a header, and tried to PDF it, I got the following error:
====================================================================== latex: Cannot start MiKTeX package manager. latex: Data: Invalid syntax ====================================================================== ! LaTeX Error: File `fullpage.sty' not found.
Since this document compiles happily in MiKTeX' editor, I assume that I am missing some simple, stupid steps.
