Tag                Name                       Managed By  Version    Alias
3.15-dev-32        Python 3.15.0rc2 (32-bit)  PythonCore  3.15.0rc2  python3[-32].exe, python3.15[-32].exe
3.15-dev[-64]      Python 3.15.0rc2           PythonCore  3.15.0rc2  python3-64.exe, python3.15-64.exe

Notice that the 3.15-dev[-64] part is correct but the python3[-32].exe is not. We should mark the [-64].exe in the aliases.
