WAIK silent install

could you guys help me with an autoit scritp? i actually made it and everything is ok.. the only step that gets stuck is at the end of the installation when i have to click on the close buttons.

this is my script, i can't figure ot whjat the problem is because everything is working except for that last step .

the program that i'm trying to install is WAIK. i extracted the components needed from the iso. which are :

• Neutral.cab
  
• aikx86.cab
  
• WinPE.cab
  
• wAIKX86.msi
  

#region - wAIKX86 install script - (Automated with WinWait functions)

$splash = 0
; Default catagory folder in startmenu.
$group = ''
; New catagory to move the default folder into.

; Installation folder in Program Files.
$directory = ''

; Run the installer.
