ts4_x64.exe is gone

Because saving builds in the game is currently broken (shows an error that it could not complete the request... every time), I found that selecting DirectX 9 fixes this. Unfortunately, doing this also mysteriously deleted the ts4_x64.exe application. I repaired the game and then found the game's folders via selecting Properties in the EA app. The folders have all the necessities to run the game but ZERO sign of the .exe application. I have looked and re-looked. It is gone. How do I make it return? Do I uninstall the game at this point and reinstall it?
