Install Tekkit Classic

Step 1

Installing a modpack using the Technic Launcher is easy. If you don't already have the launcher downloaded, visit our download page to get the latest version.

Step 2

Type in the modpack name (Tekkit Classic) or paste the following url into the search box.

Step 3

Finally, click Install at the bottom right of the launcher after you select Tekkit Classic from the list on the left. The launcher will handle everything else!

run launch.bat file, you may want to edit the amount of ram. The file gives the server 3gb on default

I am trying to create a private server for my friends and I, but every time I run the launcher.bat, it gives me this [SEVERE] Unable to process our input to locate the minecraft code How can I fix this? I ran it as administrator and it says that it fails to access Tekkit.jar
trjr101 10 months ago
I figured it out, you're supposed to change the launch.bat so it uses Java 8 instead of Java 10/11. You do that by replacing java with "C:\Program Files\Java\(java version)\java.exe"

I'm having issues where I only hear the mods custom sounds and none from the base game, it seems like everyone else too. Is this issue even being looked into?

I made a multiplayer server, but skins aren't visible to anyone. Not even I can see mine. Does anyone know how to fix it?
MagmaCourtney 1 year ago
This was caused by two separate issues, first, Mojang changed the skin update system in 2015 and 1.2.5 could not longer receive skin updates, and then in February 2018 they discontinued the legacy APIs. You can, however, download a fix for it here: https://zachary2897.com/post/172048086129/tekkit-classic-skin-fix - This fix is installed by adding the files to modpack.jar, client-side only.

This was released 4 or 5 years ago. I don't think they will do that. This is on Minecraft 1.2.5

it seems that after mojang was bought by microsoft they removed legacy files from their server... UGH... the only way to have sound back right now seems to be to get them from other source and add them manually....
