I think the answer un this article may help: https://community.sitecore.com/community?id=community_question&sys_id=d10043b31be205d0e55241dde54bcbcf

In short, replace the following in prerequisites.json

"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"

Or try direct link to download: https://docs.microsoft.com/en-us/iis/install/web-platform-installer/web-platform-installer-direct-downloads

  • thank you that solved
