@REM Abstrakt v6 silent uninstall script (prod)
@REM Stops processes, removes the AbstraktCrashMonitor service, runs the NSIS uninstaller,
@REM cleans up leftover files and stale registry entries.
@REM Prod is a per-machine install -> requires Administrator. Self-elevates if needed.
@REM User data at %LOCALAPPDATA%\Abstrakt is preserved (deleteAppDataOnUninstall: false).
@REM
@REM To deliver to customers: rename to uninstall-abstrakt.bat and email it.

@REM ======== Step 0: Self-elevate to Administrator ========
net session >nul 2>&1
if %errorlevel% neq 0 (
    echo Re-launching with Administrator privileges...
    powershell -NoProfile -Command "Start-Process -FilePath '%~f0' -Verb RunAs"
    exit /b
)

set "INSTALL_DIR=%ProgramFiles%\Abstrakt"
set "UNINSTALLER=%INSTALL_DIR%\Uninstall Abstrakt.exe"

@REM ======== Step 1: Kill any running ABSTRAKT processes ========
taskkill /IM "Abstrakt.exe" /T /F >nul 2>&1
taskkill /IM "monitor.exe" /T /F >nul 2>&1

@REM ======== Step 2: Stop and remove the AbstraktCrashMonitor service ========
net stop AbstraktCrashMonitor >nul 2>&1
sc delete AbstraktCrashMonitor >nul 2>&1

@REM ======== Step 3: Run NSIS uninstaller ========
if exist "%UNINSTALLER%" (
    echo Running uninstaller: %UNINSTALLER%
    @REM /S = silent. _?=path keeps uninstaller pinned to its location (we delete it after).
    "%UNINSTALLER%" /S _?=%INSTALL_DIR%
    echo Uninstaller exit code: !errorlevel!
    timeout /t 2 /nobreak >nul
) else (
    echo WARNING: Uninstaller not found at %UNINSTALLER%. Will still attempt cleanup.
)

@REM ======== Step 4: Force-delete install folder if anything remains ========
if exist "%INSTALL_DIR%" (
    echo Removing leftover install folder: %INSTALL_DIR%
    rmdir /S /Q "%INSTALL_DIR%" >nul 2>&1
    if exist "%INSTALL_DIR%" (
        echo WARNING: Could not fully remove %INSTALL_DIR% (some files may be in use).
    )
)

@REM ======== Step 5: Sweep stale Abstrakt uninstall registry entries ========
@REM Too complex for pure batch -- use PowerShell inline (powershell.exe is on every Windows).
powershell -NoProfile -Command "$hives=@('HKCU:\Software\Microsoft\Windows\CurrentVersion\Uninstall','HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall','HKLM:\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall'); foreach($h in $hives){ if(-not(Test-Path $h)){continue}; Get-ChildItem $h | ForEach-Object { $p=Get-ItemProperty $_.PSPath -ErrorAction SilentlyContinue; if($p.DisplayName -imatch 'abstrakt' -and $p.InstallLocation -and -not(Test-Path $p.InstallLocation)){ Write-Host \"Removing stale uninstall entry: $($p.DisplayName) -> $($p.InstallLocation)\"; Remove-Item $_.PSPath -Recurse -Force -ErrorAction SilentlyContinue } } }"

@REM ======== Step 6: Verify uninstall ========
if exist "%INSTALL_DIR%\Abstrakt.exe" (
    echo WARNING: Abstrakt.exe still present at %INSTALL_DIR%. Uninstall may have failed.
) else (
    echo Uninstall verified: %INSTALL_DIR% cleaned up.
    echo Note: User data at %LOCALAPPDATA%\Abstrakt is preserved.
)
