The installer has encountered an unexpected error installing this package.

今天安装svn的时候报错：The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2503.
解决方法：
用管理员权限打开cmd，然后输入命令

msiexec /package C:\Users\asus\Downloads\TortoiseSVN-1.14.1.29085-x64-svn-1.14.1.msi

其中msiexec /package 后面接的是你的安装程序的路径，回车运行后成功下载。
