tikz and texmaker

[Astrid Piconese]

Hi, I want to use the package pgfplots in texmaker, to create graphics.

After the simulation, there is the error:

 

LaTeX Error: File `tikz.sty' not found. Type X to quit or <RETURN> to proceed, or enter new name. (Default extension: sty).

I don't find the required file tikz.sty on internet ...

In the file pgfplots.sty, we can read:

% BEFORE the first \usepackage{pgf}, \usepackage{tikz} or

% \usepackage{pgfplots}.

% Default is

%   'dvips' for 'latex'

%   'pdftex' for 'pdflatex'

% -> dvipdfm needs special attention.

\RequirePackage{tikz}

\def\pgfplots@texdist@protect{\protect}%

\input pgfplots.code.tex

\usetikzlibrary{plotmarks}

Maybe I haven't the package tikz??

Can you help me??

Thanks!

I have see (in the Package Manager) that the pgf package is not installed.

I have tried to install it, both with and  without the administrator right, but there is an "error message": 

Does anyone know if this is related to my problem?

thanks

That is a MiKTeX error, not a LaTeX error. You need to ask about this on the MiKTeX support mailing list.

The error message (get proxy host by name failed in tcp_connect) implies that there is a problem with your Internet connection: MiKTeX was unable to look up the name of the proxy server. Perhaps you were trying to do this behind a firewall (company network, university network, etc) that does not permit the use of named proxies? Or requires you to configure your connection with an explicit proxy address instead of auto-detect.
