FOr past 3 month I have been having this issue whenever I do administrator run it say doesn't match with version but if I do normal it doesnt say anything and runs it.. So some of my apps are impossible to run also ALOT of dlls are missing and most of my games are saying your dll missing blah blah blah I downloaded them but they had the side effects: Sound is gone but game is playable/ Game LAGS and stays at 30fps for NO Reason at all (where as it stood on vsync 60fps all the time
