Re: "Side-by-side" error...?
run the file checker app from Grey link
side-by-side is something new in windows NT6.0 (vista, win7) is part of that winsxs folder in windows folder
sometimes side-by-side errors are caused by bad programing, some nero apps suffer from that. GTA4 shouldn't suffer from bad programing since you are the first to mention side-by-side and GTA4 in same sentence, you might have files corrupted
Windows 8 the next big failure, right after Windows ME
