win8系统在安装msi文件时遇到2502和2503错误

Win8系统安装msi文件时遇到问题，弹出两个对话框：
The installer has encountered an unexpected error installing this package.this may indicate a problem with package.the error code is 2502.
The installer has encountered an unexpected error installing this package.this may indicate a problem with package.the error code is 2503.

这是Win8系统的权限问题，可以如下解决:
1.运行CMD（管理员）
2.输入以下命令： msiexec /package "你安装程序包的路径"
