大家好，这是我在这里的第一个问题，所以对于任何错过的期望，我深表歉意。

从 https://eclipse.org/downloads/download.php?file=/oomph/products/eclipse-inst-win64.exe 下载 Eclipse
64 位 Windows 8
JDK 目录：C:\Program Files\Java

我需要为我的计算机科学课程安装用于 Java 编程的 Eclipse IDE，我已经尝试了两天，但没有成功。我尝试了 64 位和 32 位安装，我得到了完全相同的错误。这很令人沮丧，因为每当我搜索时，人们谈论的都是“插件”。
这是我安装时遇到的错误：

如果需要，还会继续发布整个内容，但希望有一些明显的我遗漏的东西。我尝试重新安装JDK，重新启动，重新下载Eclipse，安装Eclipse 和JDK 的32 位版本以及两者的64 位版本。我还将系统恢复到启动之前的任何状态，并在干净启动时再次尝试并得到相同的错误。
【问题讨论】：
-
你到底是怎么安装的？你是从 Eclipse 网站下载的吗？使用确切的 Eclipse 和 JDK 版本更新问题。
-
你能提到你的JDK安装目录吗？
-
64 位还是 32 位 操作系统，你用的是哪一个？
