Ok after a while I made sure to uninstall every little bit of the software before launching the new installer, I had installed an old version before so I went and deleted everything from:
/Library /Application Support/Line 6
/Library/Audio/Plug-Ins/Components/Helix Native.component
/Library/Audio/Plug-Ins/VST/Line 6/Helix Native.vst
/Library/Audio/Plug-Ins/VST3/Line 6/Helix Native.vst3
/Library/Application Support/Avid/Audio/Plug-Ins/Line 6/Helix Native.aaxplugin
This made it work, thanks for all the answers and hope this info is useful for somebody who has this problem un the future, if not then delete this thread
