I wanted to make install a mod which is ,,for Minecraft 1.7.5 or older'' as author says. Wait, are 1.7.5 mods compatibile with 1.7.10?

I installed recommended Forge version by installer, started minecraft launcher and clicked play. Launcher disappeared. That's all that happened. No Minecraft process (I know it's java something in processes). No log becouse Forge didn't even finish setuping (it does on 1st launch of Minecraft with Forge).
