Are we talking Technic Launcher or Minecraft Launcher ? If Technic how do i download just the vanilla 1.7.10 (The modpack was OG for 1.6.4 so for 1.6.4) ? If Minecrfta Launcher should i just create a modpack folder ? Thanks for the reply !
EDIT: Sorry am stupid, installed the vanilla in Technic Launcher and moved the files from the OG to the new install but not sure if i should overwrite files or not ? When i overwrite i get error when i press "play" when i dont overwrite mods dont load..
