Wild guess: What's the value of `TeX-modes' in the setup above?

,----[ C-h v TeX-modes RET ]
| TeX-modes is a variable defined in ‘tex-site.el’.
| 
| Its value is
| (tex-mode plain-tex-mode texinfo-mode latex-mode doctex-mode)
| 
| List of built-in TeX modes redirected to AUCTeX modes.
| 
| This variable can’t be set normally; use customize for that, or
| set it with ‘TeX-modes-set’.
`----

If that variable has sane values, then please do:

• emacs -Q
• eval:

    (progn
      (package-initialize t)
      (package-activate 'auctex))

  and open a .tex file.  If that works as expected, your AUCTeX
  installation should work and we have to look somewhere else.

HTH.  Best, Arash
