How do I update Forge?

[Gumball]

Some mod (I think NEI) demands I install a newer version of Forge in order to work. I wanted to know if I can just run the WinInstaller of the new version or if I have to uninstall the old version somehow.

 

These are informations that may be useful:

 

I use Minecraft 1.7.10.

My Forge Mod Loader version is 7.10.85.1291.

The little private server I play in with my friends runs Forge Mod Loader version 7.99.4.1448.

My local Forge version is (I think) 1.7.10-Forge10.13.2.1291\1.7.10-Forge10.13.2.1291-natives-70425939476642

My Server Forge version is (I think) MinecraftForge v10.13.4.1448

 

I get the following error message when trying to start my minecraft:

 

Forge Mod Loader has found a problem with your minecraft installation

The mods and versions listed bellow could not be found

Forge : minimum version requires is 10.13.3

 

The file 'ForgeModLoader-client-0.log' contains more information

 

Thank you.

If you run the installer it will create a new version in the launcher and update the "Forge" profile to that new version. If you are using a different profile, change the version in the profile settings after running the installer.

 

Thank you. It worked exactly as you said.

Wait how do I run the installer to create a new version? I'm on Mac.

The installer is just a Java program, make sure you have Java installed correctly and double click the jar file
