Hi Dereje,

Two things:
1) Pygmentize is a python package. I hope you meant trying to install it for python, and not Latex or Emacs.
http://pygments.org/docs/cmdline/
2) Which Tex software are you using? I recall having some compilation errors (last year) when I was setting this up with org-mode. Though I can't put my finger on what solved the problem, it was after I installed TexMaker. A friend suggested that it has a very decent library.

So, if you have installed the vanilla Miktex, or something else, I'd recommend giving TexMaker a try. Don't recall ever having to open it up though.

Let us know. Good luck.

I saw that there is one error:

and a warning:
 
"Package inputenc Warning: inputenc package ignored with utf8 based engines."



Do you think it would be better to reinstall emacs?

So, it looks like LaTeX is now being found but that there are errors in
the LaTeX created by org.  Have you looked at the LaTeX output buffer,
as the error message suggests?

> Debugger entered--Lisp error: (error "File

The error will likely be near the end of the buffer.
