我们在安装新的myeclipse的时候，可以会遇到这样的错误，我在网上搜索了一下：

网上给出的答案最多的是：
1. 安装路径包含中文。 可惜我开发软件很少用中文目录，没则！
2. 重新下载安装，不求甚解，考虑时间紧迫可以采纳。
3. 请用管理员身份运行， 邪门。 不知道是谁想出来的。
4. jdk运行版本不兼容， 可能。
后来我分析了一下啊，我是把其他机器上myeclipse打包拷贝过 而导致启动报错。
在进过一番搜索和分析，我们知道myeclipse是eclipse的一个插件大咋会的壳软件。是不是这个壳加载错误，导致了myeclipse的启动错误。
于是我在原来的myeclipse的安装目录下找到原来的eclipse的目录，其下有一个links目录，其中有个链接到myeclipse的外部链接配置文件。
现在大家应该明白了吧！
对就是这个配置，我打开一看，原来是文件的路径完全对，修改后，保存，启动正常。

对于从别的电脑拷贝来压缩的myeclipse，如果两台电脑的安装路径不一样会产生上面的问题
找到MyEclipse 6.0/eclipse/links/com.genuitec.eclipse.MyEclipse.link 修改里面的路径
