    Got two errors during installation but install said it completed OK. When I tried to ope the designer it failed to open. Same for the creator. What's wrong with your apps?

      What Qt version did you install and how? Attention: Qt6 does not support Windows 7!

        Hi, and welcome!

        @pjones said in Qt failed to install properly on Win7 64bit:

        Nothing's wrong with them. The latest Qt Creator is built with Qt 6, which cannot run on Windows 7 as @Christian-Ehrlicher said: https://doc.qt.io/qt-6/supported-platforms.html

        If you really truly must keep using Windows 7, then you'll need to download an older version of Qt and its tools. Probably Qt Creator 5.0.3.
