Question

过去两天我一直在尝试安装SQL Server Express 2017，但安装完成时出现了无法安装数据库引擎服务和SQL Server Replication的错误。我也收到此错误弹出消息：

发生以下错误：对象引用未设置为对象的实例。

为了解决这个问题，我还尝试了以下步骤： i）使用.NET修复工具包检查并修复我的PC的.NET v4.6。 ii）将SQL Server数据库引擎配置更改为 NT AUTHORITY \ NETWORK SERVICE 以及 NT AUTHORITY \ SYSTEM 。 iii）尝试使用修复工具在安装后修复系统。

安装中的错误日志：

and the error log after repairing the instance:

如果有人可以提出新的解决方案来解决这个问题，那就太好了。（虽然对MS SQL Server来说是全新的）

Answer 1

好的，显然我并不知道Windows SQL Server 2017 Express不支持64位处理器（顺便说一句，我的是这样）。所以我决定只获得Windows SQL Server 2016。

但是，Windows SQL Server 2017 Server Management Studio支持具有WoW64系统兼容性的64位处理器。
