I just looked back in discord history, it looks like they used Java 10, while tekkit classic is (I think) Java 7 max. Potentially Java 8 max. Do not use Java 9 or higher than that. Also please make your own posts in the future instead of necroing almost 2y old threads. This thread can walk around already...

Have you tried *any* other modpack?

Try it again without Optifine.

Everytime you install the online version of java, you install 32 bit. Use the Offline 64-bit version instead.

Eh, Pyker has been updating the launcher a couple times recently. Everytime the launcher is updated, the launcher icon is removed for a moment. I would imagine that would be their issue, but yeah, that video would help, still.

[17:09:59] [Server thread/INFO]: You need to agree to the EULA in order to run t he server. Go to eula.txt for more info.

Anyhow, I contacted PlowmanPlow, who may reply at a later point.

Ah, you seem to be a bit confused between discord and IRC. It's quite a regular thing to be waiting for a couple hours for an answer on IRC.

Yeah, rip waypoint file of your minimap. That, or the config file. Delete whatever's at the the end of the filepath you got, just after "java.lang.RuntimeException: Unknown character '".

It would probably help if we knew what the modpack is.

What account. What kind of account details are you using? Technic account or Mojang account?

You cannot allocate 4 GB RAM if you don't have 4 GB free when you try to start the modpack.

Yeah, just don't use a cracked launcher.

You, uhh, mean Tekkit Classic?

How is this relevant in any way on this very old issue, regarding someone with the Dimdoors issue which is resolved by removing the Dimdoors/DimensionalDoors folder from the world save?

Neither will the dropbox link work, as it doesn't take .rar's, only .zip files.

Cracked launchers are not supported here. Cracked launchers can burn. We do not make a cracked launcher.

This particular bug only seems to affect people if they're using: 1.) Pirated launchers 2.) Have Turkish language on their pc.

More like assuming they didn't use MCLeaks...

If you downloaded the "Online" version of java, you did not download the 64bit version of java, but the 32bit version. Download this java instead. https://javadl.oracle.com/webapps/download/AutoDL?xd_co_f=MzU4MDhjZTAtNjI4ZS00N2ZlLTk4NzEtN2U3ZDIxMzk0NzVk&BundleId=242060_3d5a2bb8f8d4428bbe94aed7ec7ae784

You seem to be using Forge 2854, probably universal. Don't. Replace the universal with the installer. Do NOT extract. Do NOT install. Use the installer as if you were using the universal.

You are using Forge 1.12.2 recommended? Follow the modpack guide like normal, but substitute the forge universal with the forge installer. Use the installer as if it was the universal file. Do NOT install or extract.

Don't get the Universal, use the INSTALLER just like you would use the universal.
