The application was unable to start correctly (0xc000007b).

I created a application using qt.It was working fine after a while i noticed that when i try to build & run it from qt creator it works both in debug & release built but when i try to lunch the application without the qt creator this error pops up "The application was unable to start correctly (0xc000007b)."(I've used the windeployqt.exe to get application dependencies).I've tried solution from previous similar topics but still no help.Would be great is someone could help me on this.Thanks

QT Version:5.12.0
Compiler:MinGW x64

May be you are missing some DLL can you check with http://www.dependencywalker.com/ for missing DLL.
It can also be possible that some of the DLL conflicts 64/32 bit DLL's.

@Ratzz Thanks for the reply.But i also tried that and added missing dlls but still the same issue.

did you use the correct windeployqt.exe ? each install has its own windeployqt.exe. One for each compiler and each version.

Also, did you add your qml files to the exe call, if you use qml=

Do you have two versions of Qt ?
Can you check if 32 and 64 bit conflicts?
