I made an autoit script for installing Easy CD-DA Extractor, but sometimes it works and sometimes it doesn't and when it doesn't the option for disable the check box doesn't work either. Here's my script: ; Setup Begins Run("EasyCDDA.exe") ; Next and uncheck checkbox WinWaitActive("Programa de instalación de Easy CD-DA Extractor") Send("!s") Send("{ENTER}") ; Begin uncheck checkbox Send("{TAB}") Send("{TAB}") Send("{TAB}") Send("{TAB}") Send("{TAB}") Send("{SPACE}") ; Confirm checkbox window
