Answer 2

你好，

请参考微软文档：VCRuntime: Command line option syntax error. Type Command /? for Help.

原因：

If the non unicode language is set in the operating system to a language such as Japanese then the win32 cabinet extractor can't handle the unicode characters in the username and will fail.

解决方案：

请检查你的文件夹目录是否包含unicode字符，如果有请将临时环境变量更改为全英字符，然后重新安装Visual C++ 转发包
