If you find out what the switch is i'd be glad to use it but i use auto it. here is my script. Run( 'hamachi_setup.exe' ) WinWait ( "Hamachi Setup", "Welcome to Hamachi Setup Wizard" ) Send("!n") WinWait ( "Hamachi Setup", "PLEASE READ" ) Send("!c") Send("!n") WinWait ( "Hamachi Setup", "Folder for" ) Send("!n") WinWait ( "Hamachi Setup", "Ready to" ) Send("!n") WinWait ( "Hamachi Setup", "Click Next to proceed" ) Send("!n") WinWait ( "Hamachi Setup", "Setup is now ready to exit." ) Send("!L") Send("!n") Good luck!
