    Description

      Calling QGamepadManager instance gives two warning messages

      auto* manager = QGamepadManager::instance();

       

      qt warn: Failed to load XInput library xinput1_3.dll (qxinputgamepadbackend.cpp:277, bool __cdecl QXInputGamepadBackend::start(void))

      qt warn: Failed to start gamepad backend (qgamepadmanager.cpp:66, __cdecl QGamepadManager::QGamepadManager(void))

       

      And on program exit there's a crash in xinputgamepad. No other gamepad related code is called.

      This is on a fresh and updated Windows 7 64-bit install.
