    I just debugged it and got this: Exception thrown at 0x670E5DA7 (Qt5Core.dll) in qtcreator.exe: 0xC0000005: Access violation reading location 0x7E5B8721.

      Is it possible that the wrong Qt DLLs are loaded? Have you changed the PATH environment variable, for example?

          No, that's not what I meant! I meant, have you done before? Or have you installed some program that did?

            Take a look at qt.conf in the creator/bin directory. If it's corrupted then plugins wont load.

              It's not corrupted because it's a clean install

                    Best guess is that it gets wrong QtDLLs maybe via
                    path.

                      My PATH variable has zero Qt paths in it. even after a clean install.

                        from shell and see if still crash ?

                            Hi,

                            Then it sounds like a graphic driver issue then. Are you sure there wasn't any modification in that regard on your machine ?

                              You could check whether Windows Update snuck in and did anything since it last worked... :)

                                That's completely possible, thanks for your guy's help!
                                @SGaist I have no idea, it quit working while I was logged in.

                                  Hi all. Sorry to revive this topic but this problem has occurred to me as well but on an application I wrote for a client. The application was running fine. Then it crashed (just like @TMcSquared ) and hasn't opened since.
                                  My access violation is in the QtWidgets.dll module.

                                  Any clues? (i don't have the welcome/QmlDesigner/etc modules to disable on load as does qtcreatorI)

                                    Hi
                                    Do you use QML?
                                    if yes, could be a driver issue.

                                    Do you have data files?
                                    if yes, it could be damaged data files crashing app on load.

                                    It could be client installed other app using Qt dlls and now your app finds the wrong version of Qt dll.

                                    Buts its nearly impossible to guess on without far more concrete information :)

                                        Hi

                                        This is reproducible only on the client pc. Any way I can debug this?
                                        Not really. you can ask him to update drivers and also
                                        collect information about opengl version supported.
                                        I take it, the project does use QML?

                                        Any idea on how I can help gather more info for furthur debugging?

                                        Well, i would add some logging to the app.
                                        So you can see if dies before main.
                                        That will give a hint if its related to actual user code or a DLL issue.

                                          @mrjj doesn't even start, so adding any logging is futile. Double click on app -> immediate crash. I can see the crash errors in the windows EventViewer
