When I Log In To The Technic Launcher I Select A Modpack Make Sure Is On The Latest Or Recommended Build Version Save The Setting Then I Click The 'Launch' And Then It Goes On Like It Normally Would But The When The Minecraft Window Opens It Stays White For 5 Seconds The Closes And I Am Left Confused And Angry Why This Had Happened To My Technic Launcher Because I Have Been Running My Technic Launcher Without Java For A While And Have Not Had This Problem Once Until Now

He's wrong. There is something else happening here that is not launcher related. Does it crash midway through a window that says FML is setting up your environment (or something along those lines)?

If so see my post here:
