    and it still crashes ? wow. thats new.
    Do you have sessions enabled ?
    also , have you tried starting it from a shell (cmd)
    to see if anything is written ?

    also when starting in cmd.
    try adding
    -noload Welcome

      I get a segmentation fault when I run it from the cmdline both without and with arguments.

        There's, oohh, a 1% chance that if you try running Qt Creator from within a debugger like Visual Studio (if you have that...), when it faults you'll get enough information from the stack trace to hazard a guess as to where it's going wrong...

          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?

            Qt has to stay free or it will die.

                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.

                                  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... :)

                                      @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 :)
