Can not install Qt Creator on laptop because buttons are off-screen

(I'm just guessing that "QT Installer Framework" is what the Qt Creator installer uses.  Please re-direct this bugrep if needed; thanks)

It's almost impossible to install Qt Creator on a consumer-sized Windows laptop in landscape orientation because the installer windows contain buttons at the bottom which are not visible (and thus not clickable), because the windows are too large to fit in the available screen space.  The buttons can not be brought into view because scroll-bars are not enabled.   All you can do is hit Enter to take the default, or semi-blindly press Tab to select a different (unseen) button and then press Enter.

The windows should be sized to fit the available viewport, or else enable scroll bars.

I'll attach a screenshot from my Yoga 13 windows laptop.  The install screen has some buttons at the bottom but you can't see them and they can't be scrolled into view.

P.S. In most cases the majority of the window is empty space, and there is no functional reason to make them larger than the available viewport size.   But if they must be larger than the viewport, then scroll bars should be enabled.  The situation is exacerbated because the installer's windows do not have normal win10 decorations, so can not be resized in the normal way with the mouse.
