Answer 1

[install files folder]\Prerequisites.json这可以通过更新文件并重新尝试安装来解决。

只需按如下所示更改DefaultValueJSON 的键即可。

"WebPlatformDownload": {
   "Type": "String",
   "Description": "Download location of Microsoft Web Platform Installer 5.0",
   "DefaultValue": "https://download.microsoft.com/download/8/4/9/849DBCF2-DFD9-49F5-9A19-9AEE5B29341A/WebPlatformInstaller_x64_en-US.msi"
},

如果以后再次失败，只需返回下载页面即可。
