    Qt-Creator 4.7.0 on Windows 10
    I think I overloaded it clicking on settings(not exactly sure though)
    I don't think the gfx driver's an issue because it was running fine yesterday, and I haven't had anything change on my machine.

      Yes, Qt-Creator just won't open at all, even after I re-install the entire thing.

        Ok, that is odd.

        there is
        C:\Users\username\AppData\Local\QtProject
        C:\Users\username\AppData\Roaming\QtProject
        which can be left over even if reinstall.

        It should be pretty safe to delete, but Creator will forget anything then.

            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

                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

                                already did that.

                                  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 ?
