Here's how you install forge:

:Search %appdata% then go to Roaming folders then click .minecraft
:open the bin folder then open the minecraft jar file with winrar
:Delete the Meta-Inf folder inside then put all the files inside the downloaded forge zip into the minecraft jar folder.
:Open Minecraft and if it didn't crashed and the main menu includes the mods,it means you have succesfully installed forge.
