Description

Brief description of your issue

Winget downloads/uses an incorrect platform for installers

Steps to reproduce

at some point in history install tailscale.tailscale on a 64bit amd system (likely need to somehow use an older tag/branch/commit in winget-pkgs)

try to upgrade an existing installation of tailscale

> winget upgrade tailscale.tailscale
Expected behavior

the upgrade happens

Actual behavior
Found Tailscale [Tailscale.Tailscale] Version 1.82.5

the error from the logs is

MSI (s) (AC:88) [12:50:39:657]: Product: Tailscale -- Please download the MSI package that is appropriate for your computer's CPU architecture.

as you can see the winget download the 32bit installer and is attempting to use is the x86 version not the amd64 version https://github.com/microsoft/winget-pkgs/blob/ffe1e6484ba81e7b6ad830b4d64f6d6d679c2b40/manifests/t/Tailscale/Tailscale/1.82.5/Tailscale.Tailscale.installer.yaml#L54-L63

Research direction

Start with the referenced Tailscale.Tailscale.installer.yaml entry for version 1.82.5 and reproduce the upgrade on an X64 system with winget upgrade tailscale.tailscale. Compare the selected x86 installer with the expected amd64 package, then verify that the upgrade uses the architecture-appropriate installer and no longer returns MSI error 1603.
