Installed ok on MacOs but not Android

Anyone have any idea why Back Row has installed ok on my Mac desktop computer but returns an error when I try to install it (by any means) on my Android TV box which is running an identical version of Kodi (16.1)?

Sorry to note that Sharpe hasn’t been around here for a long time. I guess Back Row is being allowed to die (aka: The End) – which would be sad as it’s the best skin I have seen.
