        @mrjj Do you need me to copy the relevant documents?
        If it is, I tried, but the situation is the same.

              well you should just list here what you are doing
              and what files you have. :)

              If it says this error when inside creator, you should consider reinstalling Qt.

                @mrjj I in using QT to engage in a senior editor, more specific details. At present, just to get the a prototype, recently for my side other things more, so this put in this period of time, now re compile the project, will offer the mistake. I have to re install a QT, but does not solve the problem.
                Please give the solution, if you can, can you give me a QQ, we have the details of how to solve the problem?
                If there is fate, may be in the network or in reality, become a friend.
                My friends are very few and need friends, especially when I have a problem to solve.
                Or you can join in (a personal project) and I need someone to help.

                  Ok, but it still not clear when this error comes. :)

                  When you try to run the project inside Creator?

                  Im not sure what a QQ is.
                  Its best to use forum as then all can see
                  and also learn or add.

                  Also, just so u know. there is also
                  https://forum.qt.io/category/36/international
                  where you might find group for your native language if
                  that makes things easier.

                      Inside Creator?
                      or if u click on .exe outside?

                            @mrjj Error occurred through the QtCreator run, but when running the PE implementation file (*.exe) also has an error occurred

                            If you execute the program directly, you will tell me that you can't locate the program entry point on the DocumentManaget_d.dll.

                                Yeah Google translate is good :) In old times no way I could talk to someone from China. Im from denmark. :) Nice to meet you.

                                It should not give error when run from Creator.
                                If from outside, its OK as it need extra DLLS.

                                Did you install from here ?

                                    If you use new menu and create default qt GUI project,
                                    can this run with no errors?

                                        Ok. If default clean new project also show error,
                                        then something wrong with Qt installation.
                                        Maybe disable Virus scanner while re-installing.
