I would try to change the mirror, you might be hitting a faulty one.

https://www.qt.io/offline-installers
Its bigger up front download but the same things that gets installed.

[lse123]

[mrjj]

@lse123
Install.

[lse123]

BUT WANTED UPDATE NOT INSTALL... WELL?

[jsulm]

@lse123 If you only want to update QtCreator and for some reason updating hangs on your machine then download recent QtCreator (not Qt!) from the link @mrjj provided and install it (you can uninstall the current one first). QtCreator is not that big.

Hi
But installing the newest version
gives the same as
Updating to the newest version.

Anyway as @jsulm says
