can you elaborate on your issue?

have you compiled the script according to the os you have such as x32 bit or x64 bit?

thanks for the reply:

Yes I did, i triet that ,many times.. all people who i send them the compiled program (have win 7 64bit) they have this problem!

I thought that this GUI is appearing because i didn't disconnect the webcam!! but look:

DllCall($user, "int", "SendMessage", "hWnd", $cap[0], "int", $WM_CAP_SET_CALLBACK_FRAME, "int", 0, "int", 0)
 DllCall($user, "int", "SendMessage", "hWnd", $cap[0], "int", $WM_CAP_END, "int", 0, "int", 0)
 DllCall($user, "int", "SendMessage", "hWnd", $cap[0], "int", $WM_CAP_DRIVER_DISCONNECT, "int", 0, "int", 0)
DllClose($avi)
 DllClose($user)

and still appears if you close the program and run it again!..until you restart your system... means what?!
