So me and my cousin what to start a lets play for hexxit but when he downloads the TechnicLauncher it just says add new pack. He runs on windows 8 and im fine running on windows 7. I think it maybe that the technic launcher doesnt support windows 8 yet. Uhh i told him to deleted and reinstall but it just doesnt work cuz the hexxit title doesnt show so its not installing the files. Thank you if u helped
