Did you download a Minecraft jar then rename it to modpack.jar? That would be why your modpack doesn't work. The modpack.jar is suppose to be a mod loader like Forge.

Here's how to add Fabric to a Technic modpack: https://fabricmc.net/wiki/tutorial:technic_modpacks

[MiaMaya]

Hello,
I downloaded Fabric, from my .minecraft and versions folder I moved it .jar file to my zip and then rename it to modpack.jar

[MiaMaya]

Thank you, Pyker! :3
