Invisible install

[RedShade]

Hello guys! Here is the code for a typical installation:

#include <WinAPIEx.au3>
$sProg = "downloader.exe"
Run('downloader.exe')
$sTitl = "0"
Do
    $sTitl = _WinGetForProc($sProg)
Until $sTitl <> "0"
Func _WinGetForProc($sProcName)
    $alist = ProcessList($sProcName)
    For $i = 1 To $alist[0][0]
        $iProcPid = $alist[$i][1]
    Next
    $aData = "0"
    $aData = _WinAPI_EnumProcessWindows($iProcPid, 1)
    If @error Then
        Return "0"
    Else
        $iWin = $aData[1][0]
        $sTitle = WinGetTitle($iWin)
        Return $sTitle
    EndIf
EndFunc   ;==>_WinGetForProc
Do
    Sleep(1000)
    $fVisible = ControlCommand($sTitl, "", '[CLASS:Button; INSTANCE:1]', "IsVisible")
    If $fVisible = "1" Then
        WinActivate($sTitl, "")
        ControlClick($sTitl, "", "[CLASS:Button; INSTANCE:1]")
    EndIf
Until $fVisible = "0" 

Help me to change the code so that the installation is invisible. Without window of installer, without AutoIT and installer icons in the system tray. Thanks in advance! Edited May 11, 2014 by Melba23
Added code tags

RedShade,

When you post code please use Code tags - see here how to do it. Then you get a scrolling box and syntax colouring as you can see above now I have added the tags.
