咋一看，太熟悉了，就去eclipse\links 目录下，发现指定的MyEclipse的路径不对。
突然想起来了，MyEclipse是换地了。
MyEclipse里面内置的eclipse找不到MyEclipse路径了，确保MyEclipse根目录在一个英文的文件夹下面，具体修改地址：
D:\安装承载\MyEclipse 6.0\eclipse\links\com.genuitec.eclipse.MyEclipse.link
具体错粗信息：

原因：安装时安装在中文目录下了。
解决方法：安装在英文目录下即可！
复制的时候，与之前的路径不一样，修改D:\安装承载\MyEclipse 6.0\eclipse\links\com.genuitec.eclipse.MyEclipse.link为当前目录即可
