Well, you can. But you have to use the online installer for that. The offline installer just ships one version, and comes with it's own Qt Creator / MaintenanceTool.

No, if you install two different offline installers side by side you'll get.

We could do that, but that would allow anyone to just install one version of Qt.

Well, I agree that would be nice. But it also opens up a can of worms ... Maybe you can file a suggestion at bugreports.qt-project.org, so that other people on the IFW can chime in?

As I wrote already, the preferred way of having multiple Qt versions installed is the online installer.
