1.7.10 Forge .jar not starting

[tollin lendon]

I do not know if this is the right place to post this but here it goes: I am trying to localhost a modpack server for version 1.7.10. When I try to start the "forge-1.7.10-10.13.4.1614-1.7.10-universal.jar" file, the mods folder and whatever else is supposed to appear doesn't, in fact nothing happens at all. But when I try to start the "minecraft_server.1.7.10.jar" I am able to join the server, but it is just vanilla minecraft. What should I do?
