Manifest With "requireAdministrator" Doesn't Require Administrator

Description of the issue

I am trying to have my GUI program prompt the user for administrative permissions on Windows (UAC), so I have a manifest file to specify that. However, it doesn't prompt UAC in any case I've tried (onedir, onefile, etc).

Context information (for bug reports)

• Output of pyinstaller --version: 6.17.0
• Version of Python: 3.13.1
• Platform: Windows (English)
• How you installed Python: python.org/downloads
• Did you also try this on another platform? No

Make sure everything is packaged correctly

• start with clean installation
• use the latest development version
• Run your frozen program from a command window (shell) — instead of double-clicking on it
• Package your program in --onedir mode
• Package without UPX, say: use the option --noupx or set upx=False in your .spec-file
• Repackage you application in verbose/debug mode. For this, pass the option --debug to pyi-makespec or pyinstaller or use EXE(..., debug=1, ...) in your .spec file.

A minimal example program which shows the error

gui.py

print("hello world")

gui.spec

# -*- mode: python ; coding: utf-8 -*-


a = Analysis(
    ['gui.py'],
    pathex=[],
    binaries=[],
    datas=[],
    hiddenimports=[],
    hookspath=[],
    hooksconfig={},
    runtime_hooks=[],
    excludes=[],
    noarchive=False,
    optimize=0,
)
pyz = PYZ(a.pure)

exe = EXE(
    pyz,
    a.scripts,
    a.binaries,
    a.datas,
    [],
    name='gui',
    debug=False,
    bootloader_ignore_signals=False,

    argv_emulation=False,
    target_arch=None,
    codesign_identity=None,
    entitlements_file=None,
    manifest='gui.exe.manifest',
)

gui.exe.manifest

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
    <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">

</assembly>

Stacktrace / full error message

There is no formal error message. The program should prompt UAC, but doesn't.

out.txt

Reproduce the report using gui.spec, gui.py, and gui.exe.manifest with PyInstaller 6.17.0 on Windows, then inspect the generated executable and its embedded manifest. Confirm whether the requireAdministrator setting is preserved in onedir and onefile builds; done means the packaged program consistently triggers the expected UAC prompt.
