Hey everyone i'm trying to write an automated install batch file for spybot, so far i have it installing the program updating running and autofixing problems. The issue though is that internet needs to be connected and this isn't the case where i want to use it (work). The three updates though are .exe files but they have no parameters built in. I can use my batch file to launch the update manually but it prompts the user where to install it (all you have to do is hit enter). How do i simulate the pressing of an enter key in my batch file so i don't have any user interaction...thanks
