Well, if the modpack you are playing is below minecraft 1.8, then yes, they will always be a non-slim skin.

Pastebin link no longer available.

Microsoft account? Log out, then log back in using the Add Microsoft account button.

Finally had some time to check. I downloaded the pack, started it, ran as vanilla. Went into the bin folder, delete the version.json and the modpack.jar. Put the Forge 2854 installer in there, renamed to modpack.jar. Observed the modpack starting with forge. Froze around startup phase 3, as I had my RAM set to a low amount, due to playing an older modpack.

Wait, how old is your CPU?

You log out, then you log back in by pressing the Add Microsoft account button.

Unfortunately for you, since your CPU is quite old, you can't go past java version 8u51. http://javadl.sun.com/webapps/download/AutoDL?BundleId=98428

Modpack is not zipped correctly. Please directly zip the bin/config/mods folder, not the folder they're in. Also, no mods included other than forge? As you are using the recommended version of Forge, use the installer "as-is".

It appears responsive. Its also a 2 GB modpack, which implies a badly done modpack at best. Cache folder, which is quite a bit over 1 GB is included. Minecraft.jar is being distributed, which is considered illegal.

How are you hosting the server? Are you hosting it on the same computer as you are playing on? If so, the server IP for you will either be localhost, localhost:8080 or 127.0.0.1 .

When you see this: Click the download link. If it downloads, just put it in .technic/assets/launcher. If it doesn't download either, you have bigger issues.

In that case: Link to modpack.

Forge update 1.12.2 - 14.23.5.2851 changed things. You need the Forge Installer renamed as modpack instead of Universal. Download and rename the Installer, DO NOT run/install/extract the installer.

New pastebin link doesn't work either, please don't make them private. Also, not a launcher issue, should go into Platform Pagoda.

First question: Why is it 1.2 GB? Probably because you are including the cache folder, which you shouldn't. (And ofcourse, you have your old modpack versions in there. Don't do that, that causes MASSIVE unneeded modpack bloat) Second question: Why am I seeing all kinds of files in the bin folder? I should only see the forge installer, renamed to modpack.jar. Not files indicating that its already installed, since that won't work. Last one: Why are you including your own old crash-reports? Second question is your issue btw.

That actually might be the issue. Set it to half of max, Java is not good with a LOAD of RAM.

Its not a launcher issue. Its you not allocating enough RAM to the game. If you can open the launcher, then its not a launcher issue. Anything that happens when starting a modpack is a modpack/system issue.

Literally just checked. TekkitMain (Tekkit) does not have autojump. Did you mean Tekkit Legends perhaps? This is only a thing in creative mode.

Why do people keep requesting help but then delete the file?

Well yes, that's a dead download. https://download.nodecdn.net/containers/reforged/modpack/nail/8.1.2/pixlemon-1-12-2-8.1.2-universal-jar.zip Unless its this? https://download.nodecdn.net/containers/reforged/modpack/nail/8.1.2/pixelmon-1-12-2-8.1.2-universal-jar.zip But that's a 400+MB file, that takes a while to download.

File has been deleted.

Attack of the bteam. Old bug related to joining servers. No fix, you just have to keep trying to join. This may take up to like 3-4 tries.

Include log. Include WHICH mod version you used.

No. 16 GB is already far too much for java. You are already cutting into your performance with that. Literally, more RAM = Detrimental to your performance. Welcome to Java.

Its not that technic doesn't work with newer java versions. It's that any modpack that's for 1.12.2 or lower will simply not work as Forge 1.12.2 and lower is not compatible with anything past java 8.
