Sigh, its gonna be a game of a thousand questions again I see...

You could probably use this. http://jenkins.liteloader.com/view/1.12.2/job/LiteLoader 1.12.2/lastSuccessfulBuild/artifact/build/libs/liteloader-1.12.2-SNAPSHOT.jar What do you need this mod for in the first place?

Use 64bit java (you are using 32bit). To install that, download the OFFLINE installer from java.com.

Which mc version?

It's because you bought the wrong version of minecraft. This launcher requires a JAVA minecraft account. Windows 10 (which, yes, is cheaper) is completely useless. In multiple ways.

What's the platform name?

Well, ofcourse that modpack isn't going to run correctly. It is a port of a Twitch modpack, ported incorrectly, and no forge was included. You'll have better luck with other modpacks.

Incorrectly zipped, but its not going to work anyways, since Forge changed their installation process.

Forge completely changed their installation process so that it only works for the vanilla client, and in extension, Twitch Client (due to that just making a profile for the vanilla client that comes with it).

No, you are trying to make a 1.13+ modpack, and Forge simply doesn't work anymore with Technic Launcher for 1.13+. ETA to be fixed: Never.

You check on mcleaks.net how to completely remove it.

Mac? Windows? Linux? Java 5? 6? 7? 8? 9? 10? 11? 12? 13? 14? (are we up to 15 yet? pls stop it Oracle). You can atleast start the modpack? -> Launcher Options -> Open Logs. Use pastebin or paste.ubuntu.com.

They probably did so by looking through my post history.

Follow the guide? https://technicpack.zendesk.com/hc/en-us/articles/204199345-How-to-make-a-Minecraft-modpack

It will be "unresponsive" until the whole modpack has started. Clicking it before that makes it worse, actually. And that's the buildcraft version check, as in, the update checker. Which doesn't work anymore for the very old TekkitMain, as it is trying to check some dropbox file that doesn't exist anymore. Buildcraft works fine...

Considering that MultiMC has a wholly different installation process, why didn't you follow the techniclauncher modpack guide?

Are you using MC-Launcher or hackphoenix?

So, did you copy this from curseforge?

So, that happened after you added MoarSigns (and its obviously from 9minecraft, baaaaad) to the server, right? Your VERY old version you got off 9mc: https://www.curseforge.com/minecraft/mc-mods/moarsigns/files/2223209 The actual next version uploaded 3 days later: https://www.curseforge.com/minecraft/mc-mods/moarsigns/files/2223519 The actual latest version that's not from the start of 2015: https://www.curseforge.com/minecraft/mc-mods/moarsigns/files/2284576

%appdata%\.roaming\.technic\modpacks\tekkitmain -> make a copy of the saves folder and put it somewhere else, like on your desktop. Do NOT put it in the tekkitmain folder anywhere.

Tekkit classic? Tekkit Lite? TekkitMain? Tekkit Legends? Sounds like intended behaviour on the modpack's side. Yes, reinstalling deletes your worlds if you don't make a copy of them.

This is only an option if the modpack is configured with Solder. If the modpack is downloaded via dropbox, (paid) google drive, (paid) mediafire or their own non-solder host, this is simply not possible.

Get 64bit java, allocate more than 1 GB. No, do not allocate the maximum option.

Your computer's own zoom is 150% or more, right?
