Checking Nod32 now. As for the windowblinds, yes it is based on the wise installer system but they modified it (Last I checked) to ask for a serial during install. Near as I can tell (The nod32 i have is already .msi based) All you do with it is call it with the /qn switch and then import your settings. The other one I know of can be opened with winrar and you can add the switches right in.
