答

发生这种情况是因为修复程序未正确安装。我做了一个手工卸载从命令提示符：

java -jar {cf_install_home}/{instance_home}/hf_updates/hf-10-00014/uninstall /uninstaller.jar

检查日志文件，发现访问错误的hf_updates文件夹。将读/写属性应用到文件夹并重新安装CF 10 Update 14.现在所有工作。

答

此答案仍适用于CF 10 Update 19.更新失败，因为安全强化程序限制对操作系统和CF实例根的访问，并且该用户无权访问hf_updates/*文件夹。一旦通过cf管理员面板授予安装工作完美无瑕。

如下只需更新卸载命令：

java -jar {cf_install_home}/{instance_home}/hf_updates/hf-10-00019/uninstall /uninstaller.jar
