Minecraft Forums

Hello. Recently vanilla minecraft has grown old to me so i wanted to throw ina few mods to spice it up. My main problem is that i dont like to gather materials and whatnot constantly, i like to build. So i wanted to throw in a few mods to assist in gathering materials and just overall helping my experience.

How i installed: Installed MCForge, Ran MC on Forge version, Closed Game, Drug mods to the Mods folder in my .Minecraft folder.

Problem: When i try to run the game i get this error:

This is whats displayed in the MC Launcer window ( It disappears then rather than the game popping up the launcher pops up displaying this, i DO NOT get a crash report being made i have checked)



Any help is appreciated! If you need the mods list let me know!

Looks like improperly installed openmods. I don't know which ones you're running as you did not submit a list of your mod file names, but you're either missing a core file or you got a wrong version or something.

The open mods i have are

OpenBlocks-1.7.10

OpenComponants-1.7.10



Is there a core mod im missing for them?
Heres a screenshot of my Mods folder:

You have open blocks in there. It says here:

http://openmods.info/

that you need openmodslib but I don't see it in there.

What are opencomponents? I thought that used to be an old part of opencomputers but deprecated now? What is that mod for?
