; tty7 Windows installer (Inno Setup 6 — preinstalled on GitHub's
; windows-latest runners). Compiled by bundle-windows.ps1, which stages the
; payload and passes every path in via /D defines:
;
;   /DAppVersion=<semver>   version parsed from Cargo.toml
;   /DStageDir=<abs path>   staged payload (tty7.exe, completions\, LICENSE.txt, README.md)
;   /DOutputDir=<abs path>  where the setup exe is written
;   /DOutputName=<basename> setup exe filename, without ".exe"
;
; Defaults to a per-user install ({localappdata}\Programs\tty7 — no UAC
; prompt), with an "install for all users" escape hatch in the dialog. The
; build is unsigned, so SmartScreen warns on first launch either way — same as
; the portable zip.

[UninstallRun]
; Stop the daemon before the uninstaller deletes tty7.exe — the running daemon
; is the locked image of that file, so removing it fails otherwise. This runs at
; the start of uninstallation, before any files are removed. The installed binary
; is this version, which understands the flag; runhidden suppresses any flash and
; the call returns without opening a window. RunOnceId keys the entry so a repeated
; uninstall doesn't run it twice.

[Code]
(* Gracefully stop the persistent daemon before we overwrite tty7.exe. We can't
  run the *installed* binary here — on an upgrade from an older build it may not
  understand --stop-daemon and would launch the GUI instead — so we extract the
  *new* tty7.exe to {tmp} and run that. It connects to the running daemon, hangs
  up every shell, waits for it to exit (releasing the file lock), then returns
  without opening a window. Best effort: any failure falls through to the Restart
  Manager backstop, and a fresh install simply has no daemon to stop. *)
