Hey guys,
i finally found the solution for the Status_Access_Violation Error:
just head to this archive: \Program Files (x86)\Steam\SteamApps\common\Arma 3 (or where ever you installed Arma 3)
->Right click on the Arma 3 folder
->go to properties
->go to security
->click on edit and give ALL groups and profiles the full access
->confirm and go to extended
->click on change right next to the current owner
->type in your pc User Name and verify the name
->apply and close the windows
now restart your pc and you should be able to launch Arma 3 again
If you still have the same issue then:
1. Uninstall the game. 2. Make a backup of Arma 3 folder in Documents. 3. Delete both Arma 3 folders in Documents and Steam: \Users\*YOUR USERNAME*\Documents\Arma 3 \Program Files (x86)\Steam\SteamApps\common\Arma 3 4. Reboot your PC. 5. Run Steam as Admin, download the game. 6. Do all the steps i gave you again
6. Try to run Arma 3 (without mods).
Hope i could help
