I hear you, but we aren't Buildcraft, we are Technic. We do the Technic/Tekkit/Yogbox, not individual mods just for you.
We don't support things outside of our scope. Installing mods in Minecraft is fairly easy (if obtuse as hell). I'm not exactly sure why you think we should help you, you are doing something that has NOTHING to do with what we do, and you are mad at us for our launcher which has done exactly what it has supposed to.
If you are asking us to make an old installer like before you can fuck right off, it will not happen. Its the same with the last three thousand people that have asked, it will not happen. Launcher or bust.
