I have recently been unable to open Arma 3. Just yesterday, all was well. I have been playing through the campaign, and have played very little multiplayer. When I attempt to launch Arma, I get an error code entitled: 0x0000005 status_access_violation.
I have googled this issue and found that it is relatively popular. Though I had many forums to look through, none of the solutions worked for me. One such solution involved adding -malloc=system into the launching parameters. This, as well, did not work. I also tried verifying the integrity of the game files via steam. This did not work.
This issue inhibits my ability to play the game. At this moment, I can no longer play Arma 3.
