Installing 3.1.100-preview3-014709 via dotnet-install.ps1 fails with unknown error

See original GitHub issue

Hello,

I tried to download an install the latest 3.1.100 preview (3.1.100-preview3-014709) via dotnet-install.ps1 script and the install process fails with an unknown error:

".NET Core SDK" with version = 3.1.100-preview3-014709 failed to install with an unknown error.
At D:\Proggen\DotNET\dotnet-install.ps1:669 char:5

+ FullyQualifiedErrorId : ".NET Core SDK" with version = 3.1.100-preview3-014709 failed to install with an unknown error.

Downloading via https://dotnetcli.azureedge.net/dotnet/Sdk/3.1.100-preview3-014709/dotnet-sdk-3.1.100-preview3-014709-win-x64.zip and manually unpacking works but there are 3.1.0 (no preview suffix!) folders all over the place.

I’m confused. Why is this package tagged as preview but has no preview folder/components in it?
