aspnetcore: .NET 7.0.0-rc1 ASP.NET Core Hosting Bundle fails to install x64 runtime/ANCM on Server 2016

I have a few Server 2016 VMs hosting ASP.NET Core 3.1 and ASP.NET Core 6 applications in IIS through the .NET Core Hosting Bundles.

Upon installing the .NET 7 rc1 Hosting Bundle, I noticed that it’s ONLY installing the x86 runtime and nothing for x64. Comparing snippets of the installation logs for .NET 6 Hosting Bundle compared to the .NET 7 rc1 hosting bundle, it seems some of the machine detection logic has changed?

I’ve even tried running the installation with an admin prompt with the OPT_NO_X86=1 flag, and it doesn’t make a difference. The only way anything x64-related installs is if I manually install the components. ASP.NET Core Runtime and .NET Core Runtime x64 will install properly when done manually. The ANCM is another story.
