首先下载KB2468871,这个我已下载,并尝试失败而得到上面的日志
http://www.microsoft.com/download/en/details.aspx?id=3556

试着安装它, 然再下面文件夹里面找缓存文件.
C:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Xml.Serialization\v4.0_4.0.0.0__b77a5c561934e089
分别拷贝到 C:\Windows\Microsoft.NET\Framework\v4.0.30319 和 C:\Windows\Microsoft.NET\Framework64\v4.0.30319 目录中

copy C:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Xml.Serialization\v4.0_4.0.0.0__b77a5c561934e089\System.Xml.Serialization.dll C:\Windows\Microsoft.NET\Framework\v4.0.30319

copy C:\Windows\Microsoft.NET\assembly\GAC_MSIL\System.Xml.Serialization\v4.0_4.0.0.0__b77a5c561934e089\System.Xml.Serialization.dll C:\Windows\Microsoft.NET\Framework64\v4.0.30319

然后再安装即可成功。
