Closing a running process....

I'm trying to close a running process and can't seem to get it working, here is the part of my script which is relavant:

The window class is ATL:00445D70, can anyone tell me what I'm missing here, the process remains running.

Function .onInit 
FindWindow $0 "ATL:00445D70"
MessageBox MB_YESNO "Would you like run?" IDYES NoAbort 
Abort # quit. 
NoAbort: 
FunctionEnd 

Where is the code to close the application? You are only putting in the window handle in $0, nothing else.

If you want to close the application, you'll have to send a window message (most application close when sending WM_CLOSE).

Thanks! 🙂 Got it working! 🙂
