Well I was installing forge for version 1.12.2 of minecraft, had already installed some mods to play (since most mods are in this version) but I got an error like that could not enter the game, then look for some tutorials and They taught how to open it without giving me errors (the launcher to enter the forge in minecraft premium) but I followed all the steps and I kept giving error and I can not open it please if someone knows how to open it answer me here.
