In general, "Dependency Walker" is your friend here, too: http://www.dependencywalker.com (I think it is included in the Visual Studio suite as well, but not sure about the 'Express' version).

In the file explorer you seem to run the /debug/ ("Build Configuration" - right-click on the project) version of your app. Are you also running the /debug/ version in Qt Creator? If not, the dependency on QtCore4.dll (note the missing 'd', as in 'debug') might now fail.

But then again, it should really not be necessary to copy the additional MinGW/Qt DLLs into your app directory when running/debugging your app from within Creator, I just checked this! Maybe verify your Qt Creator Settings, the "Qt4" node: make sure it detects the proper Qt version. I would expect that this setting then also makes sure that within Qt Creator environment the proper PATH is set.

Good luck,
  Oliver
