Hololens模拟器DEP6957部署错误排查及解决过程

背景 #

在商务笔记本上部署HoloLens 2模拟器，此前在家用PC（Windows 21H2）上可正常运行演示应用。已完成以下环境配置：

• 安装VS 2022 17.4及对应Windows SDK、工作负载
• 使用官方推荐的Unity 2020.3版本
• 尝试安装多个版本的HoloLens模拟器

遇到的问题 #

1. 旧版本模拟器 #

启动后出现认证错误，无法完成应用部署。

2. 模拟器版本10.0.20348.1528 #

启动时触发报错：

The emulator is unable to verify that virtual machine is running.
Failed to find the required partition 'MainOS' on the mounted virtual disk

3. 模拟器版本10.0.20348.1518 #

模拟器可正常启动，但部署应用时出现以下错误：

DEP6957: Failed to connect to device '192.168.191.217' using Universal Authentication. Please verify the correct remote authentication mode is specified in the project debug settings. DllNotFoundException - Unable to load DLL 'SirepClient.dll': The specified procedure could not be found. (Exception from HRESULT: 0x8007007F) [0x80131524]

排查过程 #

检查Visual Studio部署视图，确认Hyper-V等模拟器必备组件已启用。对比家用PC环境，仅系统版本存在差异：商务本为Windows 1909，家用PC为Windows 21H2。

解决方法 #

1. 升级系统版本：通过Windows Update助手及USB介质，将商务本系统升级至Windows 22H2
2. 重新部署开发环境：重新安装Unity 2020.3.2F1与VS 2022 17.4
3. 完成上述操作后，模拟器可正常启动并完成应用部署，问题解决。
