大家好，这是我的第一个问题，对于任何错过的期望，我深表歉意。

我需要为我的计算机科学类(class)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，但我得到了完全相同的错误。这非常令人沮丧，因为每当我搜索时，所有人都在谈论“插件”。
这是我在安装时遇到的错误:

如果需要的话，这会继续下去，将发布整个内容，但希望我遗漏了一些明显的东西。我尝试重新安装 JDK、重新启动、重新下载 Eclipse、安装 32 位版本的 Eclipse 和 JDK 以及 64 位版本的两个都。我还将系统恢复到启动任何系统之前的状态，然后在干净启动时再次尝试并遇到相同的错误。
最佳答案
我刚刚遇到了类似的问题。以管理员身份运行安装程序为我解决了这个问题。
因此，右键单击安装程序文件 (eclipse-inst-win64.exe)，然后单击以管理员身份运行。现在只需按照提示操作，您应该没问题。
以防万一，我没有更新安装程序，因为它会重新启动并且可能(我不确定)它不会在管理员模式下重新启动。
顺便说一句，这是在 64 位 Windows 8.1 机器上。
