This is my base script that I used for HKN, but that was before the conversion to F2P, so I've no clue if this still works. I think I had to launch manually, but I'm not sure.

Code:
//-----------------------------------------------------------
// SUBROUTINE TO LAUNCH AND RENAME A COPY OF LOTRO
//-----------------------------------------------------------
<Command RenameFromPath>
<SendPC %1%>
<Run %2%>
<RenameTargetWin %3%>


//-----------------------------------------------------------
// SUBROUTINE TO Position Windows for 2 boxing.
//-----------------------------------------------------------
<Command ResizeAndPosition>
   <SendPC Local>
      <SendWinSF %1%>
               <SetWinRect 0 0 1680 1022>             
      <SendWinSF %2%>
             <SetWinRect 1680 0 1280 800> 
//-----------------------------------------------------------
//  HOTKEY TO RESIZE, REPOSITION AND RENAME
//-----------------------------------------------------------
<Hotkey Lctrl  Lalt w>
   <SendPC local>
      <RenameFromPath "D:\LotRO\lotroclient.exe" LotRO1>
      <RenameFromPath "F:\LotRO\lotroclient.exe" LotRO2>
	<ResizeAndPosition LotRO1 LotRO2>


//-----------------------------------------------------------
// DEFINE MAIL LABELS FOR SENDING KEY STROKES 
//-----------------------------------------------------------
<Label w1 Local SendWin LotRO1>
<Label w2 Local SendWin LotRO2>



//-----------------------------------------------------------
//TOGGLE HKN MUTE

<hotkey Pause>

// SENT TO BOTH WINDOWS. ADD MORE KEY COMBO'S IF YOU WANT.
