I had a 5.15 install on my Windows 7 Machine and I tried to Update to the newest version 13.0 and it failed the installation. I tried to reinstall with the MaintenanceTool and it failed then I tried to download online and it failed followed by a offline install which failed. They all fail with the following error:

Does any one have any ideas? I tried to clean the registry.
The user32.dll file exists and the Win7 is not having an issue.

13.0 is a version of Qt Creator, which is an IDE and in the prebuilt package it is built using Qt library version 6.6.0.Qt 6 does not officially support Windows 7 anymore (see here).
The user32.dll file exists in Windows from Windows 95 up to current Windows 11, but is different in each version of Windows. New functions are added to it in every Windows release and Qt 6 uses some functions from it introduced after Windows 7. The function you get an error about was for example introduced in Windows 8. Not all programs from the Qt package use all of functionalities of Qt, so some, like linguist, may still be accidentally working on Windows 7, but it's not guaranteed.In short, if you want to keep developing on Windows 7 stick with Qt 5, as that was the last version officially supporting Windows 7. Also consider upgrading Windows if possible. Windows 7 has reached End Of Support stage over 4 years ago. It's not safe to use it online anymore.

I would gladly go back to version 5, if there was a way to install it, but the installer itself generates this error. So I am stuck. I'm trying to find a way around it manually. I had another instance on windows 10 but the drive crashed.

@dencla You can download old QtCreator installers here: https://download.qt.io/archive/qtcreator/
