Inserting Serial Keys Automatically

I need to automate the installation of some Antivirus applications. I can easily do it by utilizing the Process Class, but I also needed to know if there was a way to automatically input the serial key.

I thought I remember someone mentioning a property or something that could be used for that, but I can't remember what it was or who said it.

My searches so far have come up with nothing, so any information is appreciated.

Thanks

Some AV products support automation for deployment so I would look at that first. If that doesn't work, then you could probably use SendInput (not sendkeys) to send the input keys needed to type the product key. Depending on what type of control you are entering the serial into (ie just standard Win32 textbox(es) or something more complex) you could maybe use the send message API to set the text.

I looked into any automation support, and it seems Symantec does not provide any. So I'll look into SendInput.
