I am attempting to install Forge (to run the MoCreatures mod) for my boyfriend's little sister.
I have installed the latest version of Forge and Minecraft is up to date as well.
I installed Forge successfully, however when I attempt to launch Minecraft in the Forge profile, Minecraft crashes and the following error report appears:

I can provide any further necessary information. I tried the following fixes already:
Doing a clean install of minecraft (relocated the saves and pre-existing mods and moved them back into the .minecraft folder afterward)
Restarting the computer
Deleting Forge and re-installing
I had some trouble beforehand with Forge requesting to run Minecraft by itself first, and not recognizing when I had done so, but the clean install seemed to fix that.
