Note that the Optional Sideloader Modpack Studio is ONLY for StudioNEO, as I mentioned in my old posting. You can deactivate before starting the torrent download.
Don´t forget to extract the .7zip file(s) into a shortly named main folder without unnecessary subfolders on top of a drive, and avoid C:\ - so e.g. D:\AI-R15
