MyEclipse提示An error has occurred的一个解决方法

我用的是MyEclipse2016 CI 0,很惭愧是破解版,今早升级了之后提示An error has occurred,see the log….
然后打开了该Log文件,在文件最后面找到了错误提示:

提示找不到注册信息,有可能是因为破解的关系,所以升级后找不到,找了好久没找到解决的办法,包括删除workSpace,使用Myeclipse -clean,删除安装目录下的configuration目录下所有文件等等都不管用,因为破解的过程比较麻烦,所以不想折腾,最后误打误撞,替换了configuration目录后错误消失了。


修复过程:

1.在另一台电脑或者虚拟机或者别人的可以正常使用的MyEclipse安装目录下复制configuration文件夹下的所有文件

2.删除自己的configuration文件夹,粘贴复制过来的configuration文件夹,删除其中的Log相关文件

3.修复完成,再次打开可能需要重新配置所有东西,之前的配置在删除文件夹时一并被删除掉了,和新装的一样
