When the Arma 3 .exe crashes, there is no usable info at all for us. We can only guess what it could be, as crashes can only be debugged with access to the Arma 3 source code - which we do not have. If the latest version crashes for you, please post the following filled out. Maybe it can help us to at least get a hint what it could be. Thank you!   When does it crash for you?
(Answer here) What was the last thing you have seen before it crashed?
(Answer here) Does it crash every time or just sometimes?
(Answer here) Which Arma version and branch (Stable, Dev, RC/Sneak Peak) are you running?
(Answer here) Which Arma DLCs do you own? Karts? Marksmen? APEX? Helicopters? Zeus?
(Answer here) Which operating system are you using?
(Answer here) Are you using a custom memory allocator? (-malloc start-up parameter)
(Answer here) Please let off some steam here
(Rant here) If possible, please show us your .rpt file, e.g. via Pastebin
(Your link here) If possible, upload the last "Minidump" (.bidmp and .mdmp files) here. You can find them next to the .rpt
