Hello. I'm trying to export an Org file with some basic latex code (block
with "#+BEGIN_SRC latex :file block1.png" and "tex:dvipng" in "#+OPTIONS:")
but this shows up in the *Messages* buffer:

>org-babel-exp processing...
>executing Latex code block (block1)...
>Failed to create dvi file from
c:/DOCUME~1/User1/CONFIG~1/Temp/orgtex1376-zt.tex
>Code block evaluation complete.
>Formatting LaTeX using dvipng

The ODT document is created but, obviously, without the PNG formulas. It
happens too with inline LaTeX fragments:

Org's LaTeX preview doesn't work either. The dvi files are not being
created.

My setup includes:
- Windows XP SP3
- Emacs 24.3.1 with Org 8.2.1 (20131007 from ELPA) and AUCTeX 11.87.1 (from
ELPA); everything correctly (and cleanly) installed
- TeX Live 2013 (full install), on Windows' PATH

Standalone dvipng works ok (tried it with a small dvi file through Windows
command line) and latex too (through cmd, Org---latex & pdf export--- and
AUCTeX).

Thanks for reading.
