I installed GTA IV yesterday. I checked it by playing it for half an hour and after playing it I installed it's new patch so that it will play without social club coz previously the game wasn't able to play without social club. But after I installed the newer patch, the game didn't started but showed a message that "the ordinal 5365 was not found in the dynamic library xlive.dll". I could reinstall the game to remove newer patch and play it with older patch but the game takes more than 2.5 hours to install completely, which is difficult for me to give such long time. So, is there any way to just remove newer patch and get back older one or is there another way to play it with newer patch?
