xpdf関連のコマンドを使おうとすると，次の３つのコマンドが
動作しません．dllファイル不足のエラーが発生します．
・pdfinfo.exe
・pdftoppm.exe
・pdftohtml
なお，32bitのものは動作しています．動作は -h option を
付けて確認しただけです．
ご検討のほど，お願いします．
xpdf utilities は現在サポートしていません。
過去のものをお持ちでしょうか?
現在サポートしているもの (poppler utilities) で，-h オプションで
実行したものは以下の通りです。64ビットで実行してみました。
なおこれらは静的リンクを使っていて，特別な DLL を必要としません:
