Please post the exact error.
Either some libs are missing or you copied wrong libs.

This is entry point error which I am facing while running exe file.

@Imrank Did you copy the correct libraries? From where did you copy the Qt libraries?
Also, did you build your app in release or debug mode?

I had copied all the libraries from the Qt bin folder and also created the binary in release in mode. But still facing the same problem.

You have more than one Qt installation somewhere - I guess you copy the ones from QtCreator instead those form the Qt installation folder. Make sure windeployqt fetches the correct Qt libs and you're really linking/compiling aginst those libs.

so uninstalling the whole framework and reinstalling it from zero can fix this problem??
or should i do something else?

Never said this - I just said that you might have more than one Qt installation / Qt dlls there so you should make sure that the correct ones are pciked up by windeployqt (which currently is not the case as you can see)

Imrank

yeah I have confirmed that and also copied the dlls from the bin folder manually but the same problem still exist

@Imrank

first of, remove everything you copied manually, better yet, copy your exe to a new folder, delete the old one
Search your drive, you will have something like c:/Qt/15.2/msvc2019_64/bin , in there you will find the windeployqt.exe tool, use that! It is a command line tool so do not simply double click it and expect magic to happen! See here: https://doc.qt.io/qt-6/windows-deployment.html IGNORE everything static or building Qt related in that section
if you have trouble during use, or after you used the tool, come back and we can help more
