Can't Install Minecraft Forge

Megarexxx · December 27, 2015

I bet you all are sick of getting these. I'm trying to set up minecraft forge for my son, and am getting install errors. He's running latest Minecraft, and I'm trying to install Minecraft Forge for him. I was getting errors on 10 libraries, and have whittled the list down to 4 that I'm getting errors on. Here's the log when installing the client:
