[Linkman43]

Hey i need help. My tekkit wont work, due to it just playing as vanilla minecraft. Ive tried some things and yogsbox and voxel modpack work its just tekkit wont. what i want to know is where the mod files are saved so i can just delete them and start from a completely fresh slate.

/appdata/.techniclauncher Should be somewhere in that directory
