Just disregard that folder because it's for the new Kodi 17.0 Krypton and I guess he put it in there for people to test addons on xbmc4xbox and post results to help out the community I guess.

Only use a4x install from zip feature for addon zips. Extract fix zip from file manager, xbmc or unleashx and replace the ones in xbmc/plugins/program/a4x/resources/repositories and the ones in xbmc/userdata/plugin_data/program/a4x/repositories and it should work and rename/remove (Helix) from repos...

This makes the repos work again but auto module installation still broken. Don't mind manually installing them but addons4x deletes my modules b4 failing 2 download the updated one which breaks other plugins that rely on the same module (ex. urlresolver), updating plugins using a4x is a headache now...

Same here and script modules don't install automatically any more.
