[18:36:09] [main/ERROR] [FML]: An error occurred trying to configure the minecraft home at C:\Users\Brady\AppData\Roaming\.minecraft for Forge Mod Loader

java.lang.NoClassDefFoundError: cpw/mods/fml/relauncher/IFMLLoadingPlugin

 

You installed a coremod built for 1.7.10 or earlier on 1.10.

 

Side note: Why are you using 1.10? It was obsoleted by 1.10.2 within a week or so of the first Forge release for it.

i switched to 1.10.2 afterwards and it still crashes. I installed forge from the forge website. How do i change the coremod?

You need to remove the mod from your mods folder. Mods built for 1.7.10 only work in 1.7.10.

 

Mods usually have the Minecraft version they're built for in their file names. If you still can't find it, upload the FML log (logs/fml-client-latest.log in your Minecraft directory) to Gist and link it here.
