Just so you guys know, if you're willing to do some MSI hacking, you can actually remove all of the other files in the LuMMInst directory. Just make a note of the file names so you can remove their references using Orca or WinINSTALL LE. I've also been able to repack lsetup.exe to extract silently, as it's nothing but a WinRAR SFX archive. Unfortunately, I've also tried editing Settings.Default.LiveUpdate to have Express mode enabled by default, but that setting for some reason didn't appear to stick. I've tested all of this out and it works beautifully. With the 9/11/04 virus defs, my whole SAV install package is 11.7MB 7-zip compressed.
