<![CDATA[QtCreator does not start after fresh installation on Windows]]>Hi. I tried a fresh installation of Qt (Qt Online Installer for Windows: qt-unified-windows-x64-4.4.1-online.exe) on Windows 8.1, and I got the followed error trying to launch QtCreator after installation:

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: direct2d, minimal, offscreen, windows.

The last time I tried Qt on Windows a few years ago, I just installed it, and it just worked. Now I am a bit puzzled. There are many likely topics on the forum, but usually, it's about the deployment/redistributable of built applications, but it's freshly installed QtCreator from the official installer. I didn't build it manually. Could you please suggest how it can be fixed?

One workaround is to download an alternative version of Qt Creator (that is based on Qt5 not Qt6) that will run fine on your Windows 8.1, it can be found here:
https://download.qt.io/snapshots/qtcreator_qt5/8.0/8.0.1/238/qt-creator-opensource-windows-x86_64-8.0.1_238.exe
