I just managed to make GFWL work on patch 4, and with some help of ZolikaPatch, playing multiplayer with patch 7 and 8 users got possible on patch 4. But I still don't understand why GTA Connected does not work on patch 4. I tried bypassing the patch 4 not supported error but no hope, GTAC simply checks executable version by file size. Is there an experimental way to try GTA C on patch 4 or can you (GTA C team) add support for patch 4?
