    Sorry for this but what "DbgView" you mean?
    Should I run something in parallel?
    Shoud "DbgView" appear somehow automatically? but not in my case...

      Hi, yes start DbgView before starting Qt Creator from the CMD window. You can download DbgView here

          @peter_cz said in Application can't start because could not find or load Qt:

          "C:/Anaconda3

          is that from running Creator ?

          Seems that it loads Dlls from C:/Anaconda3 which is seems wrong.
          Mine loads from its installation folder.

                Yes, you right - it's from Qt Creator (second DbgView from CMake) but don't know why it loads Anaconda3???
                I have both system installed Anaconda2 and Anaconda3.

                  well my guess is there is a path to it. and Windows
                  gets that path first when trying to load the (Qt) Dlls.
                  But i did not see the C:/Anaconda3/ in your path dump ?

                  Can you for fast test rename the folder and see if Creator then starts ?

                    Hi, perhaps Anaconda has set an environment variable that overrides where to look for plugins, if you open a CMD window again and type
                    set
                    Is there a QT_PLUGIN_PATH or a QT_QPA_PLATFORM_PLUGIN_PATH in the list?

                      "Holy Smoke" - Qt creator starts! and CMake starts! and Anaconda2 Navigator starts!

                        Super:)
                        Please check as @hskoglund suggest.
                        It must have set some Qt settings to point to that folder.

                          @hskoglund said in Application can't start because could not find or load Qt:

                          QT_PLUGIN_PATH

                          Yup , I see it in Enviromental Variables:

                          QT_PLUGIN_PATH=c:\Anaconda3\Library\plugins\

                            Probably the QT_PLUGIN_PATH setting is needed for Anaconda3 to run, but it needs to be removed for the other guys to be healthy.

                            So, what you can do is to remove the QT_PLUGIN_PATH, open a CMD window and type control sysdm.cpl
                            Then select the 3rd tab *Advanced" and click on the 4th (lowest) button (should be named "Environment variables" or something similar) Another dialog box opens which will allow you to remove QT_PLUGIN_PATH.

                            Then if you want to run Anaconda 3, you can open a CMD window and type set QT_PLUGIN_PATH=c:\Anaconda3\Library\plugins\ and then start Anaconda 3 from that CMD window. That way the setting will affect only that CMD window and not the other Qt guys :-)
