so im trying to install vive craft and I uninstalled, reinstalled the minecraft, ran version 1.16.5, closed the app, redownloaded vivecraft-1.16.5-jrbudda-7-5-installer, ran it and made sure the launcher was closed and it would give me this samw error every time. I installed minecraft on my c drive and no where else. Dont know what to do and just beyond frustrated. Any help would be greatly appreciated.
