为什么我不能更改myeclipse 10.7 64位配置文件：myelispse.ini，更改配置参数"-vm"将无法 up.by 启动，我的操作系统是win8 64位，我的JDK工作没有任何问题。
有人可以告诉我原因并帮助我解决问题，非常感谢！
良好的配置就像这样：

>如果以1.7 JDK开头，MyEclipse 10.7 将正常工作。我看不出您的配置有什么问题 - 快速健全性检查，您确定指向的 1.7 VM 是 64 位 VM 吗？您可以通过转到命令行上的 bin 文件夹并键入"java -version"来确认这一点，以查看它是否报告 64 位 VM。
想要从 1.7 VM 开始有什么具体原因吗？即使您将默认虚拟机参数保留在 ini 文件 （1.6） 中，您仍然可以在 JRE 首选项页面上配置 1.7 JRE/JDK，并在您的应用程序中使用它和/或将其设置为工作区默认 JRE。
