So basically, what happens is i double click the technic zip and it pops up with "Install with Portable Mode or Standard" I have done it with both and by the videos it pops up with a logo of the Technic Platform and downloads it, this doesn't happen to me. It just gives me the folder which i have no clue what to do, I have also done the automator thing and that also is not working. Can anybody help me since i want some mod packs to play with in my Minecraft.
