[BUG?QUESTION?]SendInput example not working

[anatawa12]

This will result [0x0078 120] This function is not supported on this system. What's wrong?

fn main() {
    use winsafe::prelude::*;
    use winsafe::{co, HwKbMouse, KEYBDINPUT, SendInput};

    SendInput(&[
        HwKbMouse::Kb(
            KEYBDINPUT {
                wVk: co::VK::LWIN,
                ..Default::default()
            },
        ),
        HwKbMouse::Kb(
            KEYBDINPUT {
                wVk: co::VK::CHAR_D,
                ..Default::default()
            },
        ),
        HwKbMouse::Kb(
            KEYBDINPUT {
                wVk: co::VK::CHAR_D,
                dwFlags: co::KEYEVENTF::KEYUP,
                ..Default::default()
            },
        ),
        HwKbMouse::Kb(
            KEYBDINPUT {
