Hi guys. Sorry to make a new thread over this, but I have exhausted both this forum and googles search trying to figure this out. I have read the AVG7 manual(pdf) and have tried installing AVG with the appropriate switches: /HIDE /LICNO /NAME /COMPANY /DONT_RUN_APPS /NO_WELCOME code(it's a batch file called from runonceex): ECHO installing AVG7 SET SETUP="%systemdrive%\install\avg\avgsetup.exe" %SETUP% /HIDE /LICNO 123-License-number-ABC /NAME chris /COMPANY company /DONT_START_APPS /NO_WELCOME Now, without the two bold switches the installation runs flawlessly, but displays the main program and welcome screen after the install has completed :/ %SETUP% /HIDE /LICNO 123-License-number-ABC /NAME chris /COMPANY company I know the problem lies with these switches, as when I take /HIDE away I recieve an error reporting that either /DONT_RUN_APPS or /NO_WELCOME (depending on which switch is used first) is an "invalid command line arguement" Does anyone know why these switches fail to work, I am completely addled by this have been unable to find any explanation. (I have tried doing this using CMD, but alas this doesnt work either) (I have also attempted to use this method, but to no avail)
