I don't know, could be any number of things, mod incompatibilities, differing versions of Forge; this is all assuming that removing that mod stops the crashing. From what I've been seeing lately, mods are not being coded to properly report what the problems are, so that makes it a lot harder to track down issues. Did removing mystical agriculture stop it from crashing?

If it works without that mod, then chances are good the mod author released a version of their mod with a bug. Exactly where/why/what is up to the mod author to fix (if it works without that mod). You would have to wait for them to fix it if you want to use that version of the mod.

Looks like a possible problem with mystical agriculture, try removing it, if it works after that, report the problem to the mod author.

My best guess is you need the Titanium mod https://www.curseforge.com/minecraft/mc-mods/titanium If that works, I'd report to the mod author they need to update their page to list all required dependencies. *edit: annnnnd late to the party while looking stuff up lol. At least my thought appears valid

You're still not reading the description of the mods you want to use. Make sure you read the ENTIRE description, and it will tell you what mods you will also need to run them. Go back and read the description (the whole thing) for Dark Utitilies on curseforge.

1.7.10 is no longer supported on these forums due to how old it is. You will need to update to a more modern version (1.12.2+) to receive support here.

I don't know what mineshafter is, sorry.

You should update to the latest launcher, mine shows 2.1.9616

Which launcher/version are you using?

I haven't tried making one myself yet, but someone posted this link not too long ago: https://gist.github.com/Commoble/ac7d7b57c9cbbfcae310c4ab110c3cc0 Hope that helps!

https://optifine.net/changelog?f=OptiFine_1.14.4_HD_U_F2.jar Changelog states it is not compatible with forge, try one of the newer ones, but check the changelog for that version to make sure it works with the forge version you want to use.

If the mod doesn't have a newer version past 1.7.10, you would either have to wait for the author to update it, or (with permission and source) update it yourself. Mods, for the most part, will only work with the version of forge they are built with.

You will need to update to a current (1.12.2+) version to receive support here. Those versions are really old, and no longer supported due to age.

I would suggest deleting and retyping the line it is pointing to, it looks like there's some kind of characters in there between the method name and the curly brace that don't belong, as opposed to a simple space.

You can find the logs and crash reports by looking in the minecraft game directory, which you specify in your installation, or the default would be C:\Users\<USERNAME>\AppData\Roaming\.minecraft Where did you download forge and your mods? Youtube has some userful information here and there, but it is also a cesspool of misinformation and bad crap. If you downloaded forge from ANYWHERE but here, or downloaded mods from anywhere besides the authors direct website, or from curseforge, I would delete them all and download them from the legit locations.

1.6.4 is no longer supported on these forums due to how old it is. Update to a more recent version (1.12.2+) to receive support.

Does it still crash if you remove Mo Creatures? It looks to me like that mod is causing the crash.

1.7.10 is no longer supported here due to its age. Update to a modern (1.12.2+) version to receive support here.

It looks like you posted the installer log, your game logs will be in the logs folder in the minecraft game folder

No, you can have all the versions of forge install at the same time if you want. What happens when you try to run it? How are you trying to run it?

That is still not the new launcher, did you redownload and reinstall from minecraft.net?

Please post complete logs as explained in the EAQ. This will give more information to help people help you.

1.7.10 is ancient, and no longer supported on these forums. For support here you will need to be using (I believe) 1.12.2+

You did not read the pixelmon website, you are using the wrong forge version.

I would guess one of the mods is poorly written, and is attempting to load client classes in a server environment. Unfortunately I can't tell which one it is, so unless someone else chimes in with the answer, you'll have to remove the mods one (or a few) until you figure out which one it is.
