HI! This is my first post here WOOO! I was just wondering if anyone could help with the same crash I keep having. So I downloaded Minecraft Forge 1.7.10 because there are more mod possibilities than 1.8, and when I try to start up Forge 1.7.10 it will load for a sec and then crash. If you need to know how I downloaded it here you go: so I went to Minecraftforge.net downloaded the universal version of 1.7.10 and then I created a shortcut and put it on my desktop, double clicked it and selected install client, and then hit ok. Here is the report:

It looks like you didn't set up different profiles for different Minecraft versions. When you went to 1.7.10 from 1.8 you left at least one mod in the mods folder specifically Optifine.
Forge Mod Loader version 7.99.40.1614 for Minecraft 1.7.10 loading........
Loading tweaker optifine.OptiFineForgeTweaker from OptiFine_1.8.0_HD_U_H2.jar.......
The easiest way to avoid this is have different game directories selected in different profiles for different version. It makes it easier to jump between versions without having to empty mods folder every time. It also prevents you from accidentally loading saves from the wrong version and corrupting the world.
oh ok. Thx so much! Sorry about the late reply. After a while I started thinking hmmm....I wonder if it's because I have 1.8 mods in that folder lol xD
Open the launcher and down in the lower left click new profile. This will create a new copy of the now current profile where you can edit the name to something like 1.8 modded or whatever you choose. Place a check mark in game directory and edit the location by adding \directory name to the end. It should look something like this: C:\Users\YOUR NAME\AppData\Roaming\.minecraft\1.8 Modded. Now inside your minecraft folder is the new save directory (after you start MC of coarse). Just create your mods and resource pack folder in this new directory and you are good to go. You can quick change between versions and not confuse saves or mods. You will install Forge in the same manner since it is still installed in the versions folder but this profile will know what to use when you edit the version. If you want you can copy the options.txt and optionsof.txt from the main .minecraft folder into this new location so your settings are carried over. Also, when you use the same mods across multiple version you can in most cases copy those configs over to minimize setup.
