Windows plugin missing

  • Hello,
    I am trying to run a few applications I have created but keep receiving the famous error:
    "This application failed to start because it could not find or load the Qt platform plugin 'windows' in ''. " I am not quite sure why. I have uninstalled and reinstalled Qt but the issue persisted. I have looked at other forums and none of those solutions help.
    The applications were written 2 years ago and I am not sure if it as anything to do with the versions of Qt or windows.

    Thank you!

    Do the applications work when you build and run them from Qt Creator? Have you run windeployqt to deploy them?

    Which Qt version are you using? Which Windows version and which compiler?
