Eclipseがインストールできない

JAVA開発環境構築のために下記のサイトを参考にECLIPSEをインストールしていたところエラーメッセージが出てインストールできなくなってしまいました。
どのように解決したらよいのか教えてください。
お願いします。

追記

環境変数のPathにC:\Program Files\Java\jdk-14\binを追加したこと以外は同じ操作・表示・手順で行いました。
パスの設定が完了したかをjavacのバージョンを表示するコマンドで確認をするのも成功しました。
エラーが出たタイミングはエクリプスのインストーラーでEclipse IDE for java Developersを選び、インストールボタンを押してインストールバーが8割ほど進んだところで、エクリプスのインストーラーからエラー表示が出ました。
