VS2017 安装一直失败并出现错误，因为无法安装 Microsoft.Net.4.5.2.TargetingPack

Question

我尝试安装 VS2019 并重新安装了很多次，但每次安装都在中间停止并显示一条消息 Setup completed with warning .Net Framework 4.5.2 目标包未安装。

在日志中我可以看到

PackageId:Microsoft.Net.4.5.2.TargetingPack;PackageAction:Install;ReturnCode:1625;

在这个阶段我可以打开 VS 2017，但没有 Web 模板。

错误详情：

Package 'Microsoft.Net.4.5.2.TargetingPack,version=4.5.51651.1' failed to install.

Answer 1

错误1625表示：

ERROR_INSTALL_PACKAGE_REJECTED 1625 This installation is forbidden by system policy. Contact your system administrator.

根据https://docs.microsoft.com/en-us/windows/win32/msi/error-codes

我有根据的猜测是运行具有管理员权限的 vsinstaller（运行作为管理员），它应该可以解决问题。
