This error occurs now since 3 Days even after Fresh install. Even with or without Mods.
After Launching the display "Profil options loading" and so on are finish the Crash window with the error 0xC0000374 Status_HEAP_Corruption occurs.
Hope that you can find a way to fix that or know a way to fix that.

Running Arma 3 on x64 version. But even on x32 it crashes.
