App.exe exited with code -1073741819



  • I am running QtCreator with msvc2017_64. One hour ago Everything was working fine suddenly when i m running my Application its exiting with code -1073741819. After comment QtQuick.Controls 2.0 i can run my application again. I did not change anything in my Code. here people are suggesting may be this happened due to virus/antivirus. please suggest how can i debug and resolve things.



  • IIRC I had something like that in the past and it was because the exe file was linking agains a wrong qt dll version. Check in your system path if you have any qt program that is deployed with qt dll's in the same directory than the program executable. Also if you have Qt in your system path, changing the order and putting it first than other program that also has qt dll's, might make a difference.
