    My Windows dev machine runs Windows 10, but I need to deploy a Qt 6.2.0 application to Windows 7.
    I used windeployqt to collect all the Qt libraries but when I try to run the application on the target machine I get this error:

    I did a search for this error and it seems Microsoft has changed some libraries and there is no binary compatibility between the two OS.

    I know I can solve building the application on a Win 7 machine, but I wonder if there's a smarter way to do this inside my Win 10 dev machine.

      @Mark81 win 7 isn't officially supported for Qt6

      So you will have to use modified Qt6 libraries.

      see @hskoglund 's thread here:
      https://forum.qt.io/topic/133002/qt-creator-6-0-1-and-qt-6-2-2-running-on-windows-7

      for more information on how to do that.

      A: It turns blue.
