安装过程不做展示，点击安装包后，首先是选择安装位置，其次是一些配置事项，这里特别介绍一下。
Create Desktop Shortcut：创建桌面快捷方式图标
Update context menu：是否将从文件夹打开项目添加至鼠标右键
Create Associations：关联文件格式，例如.java,.groovy,.kt等，选中对应格式，即可用idea打开此类文件
Download and install 32-bit JetBrains Runtime：下载并安装 JetBrains 的 JRE
Update PATH variable (restart needed)：是否将 IDEA 启动目录添加到环境变量中，选中即可从命令行启动idea
后续安装默认下一步即可。
特别注意，最后一步安装完成后不要默认运行idea，需要先完成步骤3。
