    Could you post a screenshot of that error from the Windows 10 PC?

      While it is true that I cannot spot why you get this error message given the directory's contents, this is a quite different error message from the one you said you get, you show at the top and we have been discussing throughout this topic. Why are you now getting a different message if you said Win 10 gave you the original message? Is this a different Win 10 machine from the one you said produced the first error? It is difficult to help when you report one thing and then show something different.....

      It is possible that you could get the latest error message if the named DLL is missing one of its dependencies. You might like to load up the Windows Dependencies tool to examine this.

        Hi, just guessing but that missing dll error can occur if your app for example starts a printout and that Windows 10 PC has a older (perhaps not Qt) installation of MinGW that lacks libgcc_s_seh-1.dll and that other MinGW is in ithe path environment variable.

        To check, try building a simple app, say the Calculator Example using your MinGW 6.5.1. Then use the same windeployqt procedure you did for Elab_license_otp.exe and try the Calculator app on that Windows 10 PC.

            If you try the same Calculator example app again, but this time built with Qt 6.4.3 MSVC2019, do you get the same error?

              I wrote application on windows 11 and find way to deploy it correctly, but on windows 7 this app doesn’t work and go to same error as yours. I try to reinstall dlls, sfc /scan, Visual Redistributable but still nothing. I try this app on windows 10 if it works

                Qt 6.4.3 MSVC 2019 or Qt 6.5.1 MinGW do not support deploying to Windows 7 :-(
                Qt6 requirements here

                    Are you really asking about Qt Creator version here? Do you understand that it is the Qt version, nothing to do with Creator, which determines whether your application will or won't run under Windows 7, 10 or whatever? So far as I know any version of Creator will run under Windows 10.

                      Thanks to all for support and your valuable suggestions.
                      I am successfully made executable file using (Qt creator 5.9.5) compiler version (Mingw 5.3.0) using windeployqt.
