You are right.  With a test-example EPS which comes with TeXLive, it
again compiles well for me:

   \psfragfig[mode=errorstop,width=0.9\textwidth]{/usr/share/texmf-dist/tex/latex/mwe/example-image}

Again, in the log output I don't see preview being loaded, so I added a
\usepackage{preview} again.  With that, it still compiles well, both
with the TeXLive version of preview.sty and with the current AUCTeX
version.

However, in the log I also see these warnings:

--8<---------------cut here---------------start------------->8---
Package ifplatform Warning: 
    shell escape is disabled, so I can only detect \ifwindows.
...
Package pstool Warning: 
  Package option [process=none] activated
  because -shell-escape is not enabled.
This warning occurred on input line 163.
--8<---------------cut here---------------end--------------->8---

But when I add

  %%% TeX-command-extra-options: "--shell-escape"

I get this error:

--8<---------------cut here---------------start------------->8---

I have no clue about pstools, so I copied the image next to the tex file
so that it can write the eps-image-name.tex file.  Then it complained
about missing tikzpicture, so I eventually added

  \usepackage{tikz}
  \usetikzlibrary{calc}

and the compile worked again.  Again, the log suggestes that preview.sty
is not loaded, so again I added \usepackage{preview} and tried with both
the TeXLive and AUCTeX versions.  As you can guess, both worked just
fine.

I have no clue and no possibility to try MikTex but it seems to be
depending on distro.

Bye,
