问题现象​

  • 双击Charles无任何反应
  • 重装后问题依旧存在
  • 新安装后首次就无法启动

错误排查步骤​

  1. 通过命令行启动定位问题：
cd "c:\Program Files\Charles"
Charles.exe
  1. 观察报错信息（关键错误）：

问题根源​

Java Access Bridge（Java辅助功能桥接库）配置异常：

  • 该组件通常随JRE自动安装
  • 开发环境可能只有JDK未包含完整配置
  • 用户目录下的配置文件可能导致冲突：
    C:\Users\<current_user>\.accessibility.properties

解决方案​

方法1：删除配置文件​

del C:\Users\%USERNAME%\.accessibility.properties

方法2：注释配置内容（推荐）​

  1. 用文本编辑器打开配置文件
  2. 在所有行首添加#注释符

验证结果​

重新启动Charles应用，应能正常打开

额外说明：

  1. 推荐优先使用方法2，可作为问题回退方案
  2. 本方案适用于Windows系统，macOS/Linux用户需查找对应系统路径
