Ok so i've had far cry 4 for the longest. only running a dual core processor after struggling forever with the game cause of a "stopped working" error now have the blank screen familiar with trying to run with anything below a quad core. got dll files for fix but cant get rid of stopped working error for extreme injector. running in admin and ran .net repair programs and installed all recent ones which is only thing suggested on any forum. and others have had the same frustration with no resolve. is it because of running a 64 bit version of vista?i dont know cause after common 'remedies' if problem is unresoled i've seen people ignored so i have been unable to resoolve myself. pls help.
