Qt installer crashes, blue screen, windows 10

[Michaelis]

Hi!

I downloaded qt-unified-windows-x64-4.5.1-online.exe and tried to install Qt Creator but every time it crashes Windows 10.
I'm trying to install Qt Design Studio 3.9.0, Qt 5.15.2, Qt Creator 9.0.1 and MinGW 11.2.0 64-bit.
Anyone have any idea about what could be happening?

You want to install Qt 5.15 etc. but you have an installer for Qt 4.5.1.
Qt 4 seriously predates Windows 10, so it is probably unsurprising that there may be issues.

Try the current installer from qt.io or your commercial account if that is appropriate.
