General Discussion (dev branch) in ARMA 3 - DEVELOPMENT BRANCH Posted September 5, 2016 Will have to look again, will I see the reason? It's that "Arma3.exe has stopped working" message box. Will also run process explorer then. 8 GB RAM here. And indeed, c:\ where pagefile.sys is located has only 7 GB left. Check arma logs (.rpt) for crash info. In my case 3,5Gb of page file were not sufficient. Dunno about 7GB, since you have half of my RAM.
