安装SqlServer出现错误System.Configuration.ConfigurationErrorsException解决方法

SqlServe软件安装过程中容易出现问题，若是第一次安装失败，第二次卸载后再次安装则可能会出现问题：

System.Configuration.ConfigurationErrorsException: An error occurred creating the configuration section handler for userSettings/Microsoft.SqlServer.Configuration.LandingPage.Properties.Settings: Could not load file or assembly 'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies.

WRN: Assembly binding logging is turned OFF.
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

其原因就是如果Microsoft_Corporation文件没有删除，那么SQL软件则不能安装。

解决方法为：rd /s /q %localappdata%\Microsoft_Corporation
