无法安装 SQL Server 2017 Express 数据库引擎服务
Unable to install SQL Server 2017 Express Database Engine Services
过去两天我一直在尝试安装 SQL Server Express 2017，但安装完成时出现错误，其中数据库引擎服务和 SQL 服务器复制失败安装。我还收到此错误弹出消息：
发生了以下错误：
对象引用未设置为对象实例。
我还尝试了以下步骤，希望能解决这个问题：
i) 使用 .NET 修复工具包检查和修复我的 PC 的 .NET v4.6。
ii) 将 SQL 服务器数据库引擎配置更改为 NT AUTHORITY\NETWORK SERVICE 以及 NT AUTHORITY\SYSTEM。
iii)安装后尝试使用修复工具修复系统。

如果有人能尽快给我建议新的解决方案来解决这个问题，那就太好了。 （虽然对 MS SQL 服务器来说是全新的）
好吧，显然我不知道 Windows SQL Server 2017 Express 不支持 64 位处理器（顺便说一句，我的是）。所以我决定只获取 Windows SQL Server 2016，而不是。
Windows SQL Server 2017 Server Management Studio支持64位处理器，兼容WoW64系统
