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!

Tekkit Classic Version 3.1.2

created by sct on Minecraft 1.2.5 using Technic Solder

The Lumy Skin Patch, which was added to other legacy Technic packs, has been released for 1.2.5 in the time since those packs received it. Would it be possible for it to be added to Tekkit Classic as well?

What Java version should I install to play? The current Java I have installed for 64 bit (13.0.2) is stated to have issues with Minecraft, and runs into an error before getting to the main menu if I use it. I otherwise have to use 32-bit Java w/ 1GB of RAM, which I would prefer not to do.

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

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?
