Symptoms

1. Arma 3 Launcher
   Arma3launcher does not work that prevents the launch of the game, Microsoft .NET Framework 4.5.2 and Microsoft Visual C++ Redistributable for Visual Studio 2013 do not solve the problem, the only way to run Arma 3 is to rename arma3_x64 to arma3launcher then arma 3 will run
2. ACE3 Mod
   Запуск Arma 3 с модами ACE3 выдает ошибку в игре
   x32 Trying to load a x64 dll 'ace_clipboard.dll' from a 32-bit executable
   x64 Trying to load a x86 dll 'ace_clipboard_x64.dll' from a 64-bit executable
   
   

The same problem is observed in Wine-Stable.
But on Wine-Staging ACE3 mod works fine.

Reproduction

Start the game with ACE3 mod and see the message in the main menu

Start with arma3launcher_steam-107410.log and arma3_x64_steam-107410.log, then reproduce the launcher failure and ACE3 startup error described in the report. Compare the x32 and x64 ACE3 DLL loading messages across the reported Proton and Wine configurations. Done means Arma 3 launches normally and ACE3 no longer reports the architecture mismatch.
