MyEclipse14安装失败

今天卸载MyEclipse10 改用14，因为公司要去必须是14以上。但是安装失败。
（因为后面安装成功了，忘了截图，网上找了下面这个图片，是15的）

点击show 日志

解压后可以进入文件夹中找到oneinstall文件夹，找到errors.txt文件：

打开errors.txt文件：
++ ERROR #1

错误显示是状态异常，不能读取注册列表，我用的是win10系统，win10经常会出现一些奇怪的问题。我遇到的这个就是权限问题，只要点击右键以管理员身份运行安装就可以了。

如果遇到其他的异常：
++ ERROR #1

如果遇到其他的异常，那首先以管理员身份运行试试，如果可以就好，如果不行，在C:\Users\Administrator目录下找到.deliverycenter.installs和.deliverycenter.system两个文件 然后删掉！！ 但也可能不是这个的问题，删掉前最好备份一下。
