Hey, so I was downloading mods for my new mod pack survival for 1.7.10 and then this came up.
Forge Mod Loader has found a problem with your minecraft installation
The mods and versions listed below could not be found
Forge : minimum version required is 10.13.4.1566
The file 'logs/fml-client-latest.log' contains more information
Sorry for bothering you if this is an easy situation to fix, I'm not the best coder.
