我是64位的win7旗舰版系统，我是先把visual2010装上了，再装sqlserver2008就这样了。望各位大侠帮忙，不胜感激1！
异常信息如下：
System.Configuration.ConfigurationErrorsException: 创建 userSettings/Microsoft.SqlServer.Configuration.LandingPage.Properties.Settings 的配置节处理程序时出错: 未能加载文件或程序集“System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089”或它的某一个依赖项。系统找不到指定的文件。 (C:\Users\Administrator.ZGC-20110802FFY\AppData\Local\Microsoft_Corporation\LandingPage.exe_StrongName_ryspccglaxmt4nhllj5z3thycltsvyyx\10.0.0.0\user.config line 5) ---> System.IO.FileNotFoundException: 未能加载文件或程序集“System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089”或它的某一个依赖项。系统找不到指定的文件。
找不到的那个指定文件，即user.config那个文件是这样写的：
