    ok one last ditch: try to start Qt Creator without any plugins: open a CMD window:

    C:\Qt\Tools\QtCreator\bin\qtcreator -noload all

    if that shows you a messagebox: "Failed to load core: Core plugin is disabled" then try again but loading the Core plugin:

    C:\Qt\Tools\QtCreator\bin\qtcreator -noload all -load Core

      @hskoglund -noload all still does the same. no error message, windows error reporting just appears in the task manager for a second and the log is added.
      i tried installing directx runtimes and adding windows sdk to the environment path but still the same. old apps ive made with qt still work fine though.
      i guess i will just have to try installing on linux sometime and continue from there, im baffled.

        Hmmm, if you're curious you could always fire up the old Dependency Walker load Qt Creator into it and press F7 to start profiling it. It should show which .dll is the culprit...

          Dependency Walker makes it to IMM32.dll then freezes up, some post on stackoverflow says it may need WDK. might be awhile before can download that.

            found somewhat of a "solution", i downloaded and installed qt-creator-opensource-windows-x86_64-4.6.0 from http://download.qt.io/official_releases/qtcreator/4.6/4.6.0/ and qtcreator will actually open. have no idea why the version included with full qt and my previous installations just stopped working, guessing it has to do with 32bit versions even though ive always used 32 bit and has always worked from a fresh install of windows. thanks for all the suggestions though.

              I'm having the same problem.

              C:\Qt\Tools\QtCreator\bin\qtcreator -noload all
              

              produces an error:
              Failed to load core: Core plugin is disabled

              &

              C:\Qt\Tools\QtCreator\bin\qtcreator -noload all -load Core
              

              launches a greyed out very minimalistic unusable Qtcreator window.

              I've installed Qt 5.14 with QtCreator 4.11 (MinGW 7.3.0 32bit). Please, help.

                @jyotib When go through the plug-ins and always disable only one until QtCreator starts.
                Usually Welcome plug-in is the one causing problems.

                    You did: -noload all

                      @jsulm Is it possible that i didn't installed some components and that resulted in this situation? I followed this youtube video link text during installation. And i'm using windows 10 64 bit system.

                              @jyotib When I guess it is another plug-in. As I suggested before: go through all plug-ins and disable one in each step and see whether QtCreator starts or not.

                                  Do you mean it does not start?
                                  Any anti-virus software running?
                                  How did you install QtCreator and which version?

                                    I realize this is an old thread, but in the chance someone else stumbles upon it this while beating their head trying to figure out WHY Qt Creator mysteriously won't start anymore, I wanted to share what worked for me. After scouring the internet for hours today when both Qt Creator and Qt Design Studio mysteriously wouldn't open anymore, I found QTBUG-50371. Apparently it's still a bug, because sure enough, when I disconnected my second monitor, they were magically able to start again.
