Hi!

I am currently using Qt 6.1.0 with Qt Creator, but I need to use Qt 5.15.2 for a project.
I can't find a way to add this version to the kits of Qt Creator. In fact, I can't find where to download it to start with.

If I use the online installer, it won't let me do anything as Qt is already installed.

Is there any way to just add a previous version of Qt without using the online installer?
If so, how can I get this version?
