.net - SQL Server 2008 R2 - .NET Framework 未处理的异常

Question

我已在新 PC 上安装了 SQL Server 2008 R2。一切都工作正常，直到我开始从旧 PC 上的 SQL Server 2008 R2 管理工作室导出注册服务器。当我将其中一台注册服务器导入新安装时，出现错误“ key 在指定状态下使用无效”。

现在，每次我尝试在新安装上打开注册服务器时，我都会收到带有相同消息的 .NET Framework 未处理异常。注册的服务器区域完全是空的。现在无法添加任何已注册的服务器。我尝试重新安装 SQL，但错误仍然存​​在。这显然与进口流程有关。也许有什么东西被损坏了。有谁知道如何解决吗？

听起来像是您的 Windows 配置文件中的某些内容(例如 Windows 7 上的 Users/[Username]/AppData/Roaming)。您是否尝试过从中清除 SQL Server 条目？
