Setup fails on Windows Server 2025

[szalkerous 1]

When attempting to install the Windows Emby server on a clean Windows 2025 Standard install on a Dell PowerEdge rack server (Intel Xeon based), the setup.exe immediately fails.

Install log contains the following:

The following properties have been set:
Property: [AdminUser] = true {boolean}
Property: [InstallMode] = HomeSite {string}
Property: [NTProductType] = 3 {int}
Property: [ProcessorArchitecture] = AMD64 {string}
Property: [VersionNT] = 6.2.0 {version}
Launching Application.
URLDownloadToCacheFile failed with HRESULT '-2146697208'
Error: An error occurred trying to download 'https://embydata.com/downloads/server/release14/MediaBrowser.Server.Installer.application'.

 However, if I put that exact URL into the Edge browser, it resolves fine.

Anyone else run into this?
