Alright, where to start. First, yes, it is really quite an easy fix. Second, lets start with the fixes. Your modpack is located in a subfolder. This does not work. Your modpack contains WAY too many files, and an actual copy of your modpack. This increases your filesize by a lot. Your modpack should only contain the following folders: "bin/mods/config/servers.dat" and you should zip those files only. Do not zip the folder they are in, because that will put the files in a sub folder. Your bin folder should only contain the modpack jar file, all other files need to be removed.

ChickenCore was fine, you actually downloaded the version for MC 1.9. Which is why your pack wouldn't start. Also, you will need to have re-add the dungeonpack mod, as right now, its a .zip file of a .jar file. Which is not going to work... (so just readd the file, but make sure it is a jar file). Also, I got to another screen now, you forgot to add NotEnoughItems (needs to be atleast version 1.0.5, but just use the latest), and you need to update EnderStorage to atleast version 1.4.7 (you are using version 1.4.5 atm).

Remove the TinkersConstruct1.5.5.7 file from your mods folder, as it is for 1.6.4. Add OpenmodsLib to your pack, it will crash without it. Also, please use services like Pastebin or Ubuntu Paste to add crashreports to this topic. It shortens the page considerably.

That's the whole idea. READ READ READ.

Make sure to "update" your modpack version. This will tell the Launcher to check for a "new" pack. After that, restart your launcher.

Nothing on updating NEI to a more recent (and not year-old) version? If updating NEI, grab the more recent version of NEI integration as well.

That version.json file missing error is always given on startup. Literally every time. If something is crashing you, it should be seen farther down the log.

Now, lets start the analysis: Your bin folder is fine, don't change it. Your mods folder contains a copy of your mods folder, this pretty much doubles your filesize. Remove that copy. Your mods folder contains a few mods that are not from their original source, like Dungeonpack and StatusEffectHud. You forgot to include OpenModsLib, without it, your pack will not launch. WildCaves as included in your pack does not exist. Either use Cavebiomes or stop downloading crap off modrepost sites.

Your modpack.jar is actually called modpack.jar.jar. This has been a bit of a confusing thing around, I know, but if you were to rename the jar to "modpack" it would work. While you are at it, get NEI from the official source: http://chickenbones.net/Pages/links.html And get Extra Food from the official source: http://mods.curse.com/mc-mods/minecraft/222348-extra-food

And you forgot to add CodeChickenCore, as NEI will not work without it and will crash like this.

We weren't able to download your modpack using the link above, so we are kinda guessing what is happening. Could you update that link up there?

I told you in your last topic about this exact issue to check your dependencies.

Do you even need to ask?

And did you rename the forge.jar to modpack.jar?

Easy as pie. Grab the latest ones. http://chickenbones.net/Pages/links.html

Downloaded that modpack, it does not contain codechickencore, nor codechickenlib. You really need to add both.

Just a minor idea, but it could have something to do with the missing Forge in the bin folder. Aka modpack.jar is gone, and the normal files are there instead.

Ah, normally we need to ask for a log to find that. https://cdn.discordapp.com/attachments/96563656271093760/166334782450565121/clearJavaEnvVars.bat That's a small line of code one of the Technic moderators made. It won't come up, nor give you a confirmation message or feedback, but it removes the _JAVA_OPTIONS that block you from playing. In case you are wondering, the Java options limit any java processes to a maximum of 512MB, so even if you were to set your RAM allocation to everything you have, it would still limit it to 512 MB.

You did try to close the launcher login box, and launch it again?

You forgot to add OpenModsLib, check all your dependencies (coremods/required library-mods) for the next few issues...

You forgot to add CodeChickenCore. NEI will not work without. (Reason its crashing) You got too many files in your bin folder, you only need to add the modpack.jar, all other files need to be removed. (does not cause crashes, but can lead to issues)

@MunausPoeple are very annoying today. Also, just nope, the server is bad.

Why not just add said log or system information? Java8u25 only works for the Pixel format not accelerated issue with Windows 10 (graphics card related).

Besides that, you can only open one of each modpack. Now unless your son is going to open all modpacks at the same time...
