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

Can you run again with --verbose-logs and share the logfile?
I wonder if you had a 32-bit version installed previously, and the installer changed. I see multiple architectures in the latest version.
You may need to uninstall and then perform a clean install to get the proper architecture.
winget show <package> should show the installer URL that would be selected based on the state of the device.
You may need to uninstall and then perform a clean install to get the proper architecture.
While this workaround may resolve the issue, users should not be expected to perform this workaround.
Rather, if users are expected to perform such workarounds, they may as well forego the use of Winget and instead just manually uninstall the program, then visit the software developer's website to download the installer.
@denelon Hit the same issue today on the latest software. I haven't tried the workaround (uninstall and then perform a clean install).

I have the same issue, has been going on for a long time. Without uninstalling I can run the installer from
winget show tailscale.tailscale
and it installs fine.
