im new to the forums and am having the same problem... but only on my laptop... i open technic launcher.exe from my desktop and a small windowt opens for about 3 seconds syaing checking current version or something and then just dissappears... the launcher does not open... minecraftworks fine from the default launcher and the technic launcher works fine on my tower... i am quite computer literate but i am hopeless at programming so i just went for the .EXE launcher file, as did i on my tower which worked fine. my laptop is a lenovo T60 1951 CTO with an intel core 2 duo @2.0GHz with 2GB DDR-2 RAM... it runs minecraft fine and i just want to play on my server whils im not at home
