      Hello, my previosly working Qt program fails to run after the windows 10 update.

      Updates are:
      Security update for Microsoft Windows (KB4284835)
      Update for KB2504637
      Security update for Adobe Flash Player.

      The application fails when attempted to run with error : exited with code -1073741515.

        The program failed because windows update deleted some dll while update happened. Restoring the dlls again, fixed the issue.

          @milan said in Qt program fails to run after windows update:

          1073741515

          I searched and found out that the error means
          -1073741515 is equal to 0xC0000135 meaning STATUS_DLL_NOT_FOUND.
          It means some missing dependencies according to new link. Maybe you can try to reinstall Qt and see if it works.

            @TobbY . Thanks for your reply, but installing Qt takes a really lot time. If some other solutions exist, it would be better.

              I have searched this issue. Mostly people having problem with windows platform plugin, generally happens after windows update.
              Usefull link for same case.

                @TobbY . Reinstalling the Qt creator wont help. I tried once.

                  Hi
                  Do you mean when you run app in deployment folder, stand alone or via
                  Creator. Also are you using visual studio compiler ?

                      Hi
                      You can try to run a repair via the visual studio installer.
                      Also check your kits are ok.

                                  Yes, it won't fail if dynamic linked so just check to understand why
                                  it died running from creator.
                                  Super. thank you for the feedback.
