社会人大学院に通うTeX初心者です。論文の投稿やスライド作成のためにTeXを使わなければならなくなりました。
OSはWindows7とWindows10です（マイクロソフト製品以外は使える環境にありません）。
TeXについては、阿部先生の「TeX インストーラ 3」を使って、W32TeXをインストールでき、TeXworks上からpdfLaTeXを使って、 論文が書けるようになりました（日本語・英語）。

今度は、発表用のスライドを作らなければならなくなったので、Beamerを使ってスライドを作ろうとしています。

ネットでいろいろ調べて以下のようなことをしました。

C:\w32tex\share\texmf-local\tex\latexの直下に、
beamer
pgf
xcolor
というフォルダをつくり、この中に、
latex-beamer-3.07.tar.gz
pgf-1.01.tar.gz
xcolor-2.00.tar.gz
から解凍した中身をそれぞれ入れました。
xcolorについてはコマンドプロンプトを使って
cd c:\usr\local\share\texmf\tex\latex\xcolor
latex xcolor.ins
として、insファイルをコンパイルしました。


そして、以下の文章をTeXworks上からpdfLaTeXを使って、 スライドにしようとしました。


\documentclass{beamer}
\title{はじめてのBeamer}
\author{高木貞治}
\date{\today}
\begin{document}
\maketitle
\begin{frame}{スライド}
スライドができたよ！やったね！
\end{frame}
\end{document}

すると以下のようなエラーメッセージが出力されました。

どこが悪いのかよくわかりません。
どこを直せば、Beamerを使ってスライドを書けるようになるでしょうか？ご教示いただければ幸いです。

なお、「TeX Live」にはBeamerが入っていて、最初から使えるといった記事を良く見かけますが、

私は「TeX インストーラ 3」を使って、W32TeXをインストールしてようやくTeXが使えるようになっています。「TeX Live」に置き換える作業は自分にはハードルが高すぎて困難なので、W32TeXの今の環境をそのまま使って、Beamerを使えるようになることが希望です。
