Qt Missing DLLs

  • I created a simple notepad file using Qt.

    The program does run when in Qt creator.

    However, when I navigate to the debug folder, the created executable file does not run without DLLs.

    I've read online that this is can happen and all that is required is that the respective DLLs be copied to the location of the exe file. However... the error messages identify DLLs that my machine does not have.

    I get and error message for the following DLL files.


    I do not have the DLLs above. I do however have the dll files below. Which do not have the added 'd' before the extension.


    Any help provided would be much appreciated.

    Thank you in advance!

    If you want to use your application outside Qt Creator, you have to follow the deployment instructions. The most simple is to use windeployqt for that.
