Minecraft Forums

Ok, so I have Forge 1.7.10, and I was trying to launch Minecraft with Forge just like normal. The launcher disappeared like normal, but then came back with a new tab in it called Game Output *username*. Minecraft will now only launch with my non modded profile. Can someone help fix this? The text in the box is as follows:

One of the core mods is missing I think. Or a wrong version.
Screenshot of mod folder with file names visible in list view might help.

See if these help.

There are some 1.6.4 mods in there because I downloaded a mod pack that had some. Is there any way to get them to work with Forge 1.7.10? Do I have to download two Forges? Sorry to divert you/anyone from the original question.

There is no cross compatibility so you can't mix and match. 1.6.4 works only on 1.6.4.
If the mods just haven't been updated to 1.7.10, then you best stay on 1.6.4
You need to take out one version or the other, and then re-submit error report which will likely be different (if it errors at all).
You could just have two separate worlds?

Well, I'm still getting an error.
